Title: Data virtualization in natural language

Description:
BACKGROUND 
     Aspects of the present invention relate generally to computer searches and, more particularly, to virtualizing data in natural language searches. 
     Data virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted at source, or where it is physically located. Data virtualization can provide a single customer view (or single view of any other entity) of the overall data. Two techniques exist for data virtualization, consolidation and federation. Consolidation is a technique where there are plural data tables in a backend. Consolidation creates a sub-set of data from the data tables and brings that sub-set of the data to a single point. Federation does not bring the sub-set of the data to a single point but, instead, creates pointers to the data. To use the data, federation pulls-up an identification of each pointer to find the data. 
     In a natural language world, when a user reads through a document, references to different sections are provided and the user is able to understand the context associated with those references. Examples of such references are: “as stated earlier”; “as shown in the figure above”; and “referring to sections  2  and  3 ”. Different references to the content are created in case of natural language writing and reading. 
     SUMMARY 
     In a first aspect of the invention, there is a computer-implemented method including: creating, by a computing device, a virtual consolidation layer; replicating, by the computing device, snippets that are results of a query; copying, by the computing device, the replicated snippets to the virtual consolidation layer; performing, by the computing device and by a machine learning model, matching of particular ones of the snippets in the virtual consolidation layer; and producing, by the computing device, a search result comprising the matched snippets. 
     In another aspect of the invention, there is a computer-implemented method including: creating, by a computing device, a virtual federation layer; storing, by the computing device and in the virtual federation layer, pointers to snippets that are results of a query; performing, by the computing device and by a machine learning model, matching of particular ones of the snippets pointed to in the virtual federation layer; and producing, by the computing device, a search result comprising the matched snippets. 
     In another aspect of the invention, there is a computer program product including one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media. The program instructions are executable to: create a virtual consolidation layer; replicate snippets that are the result of a query; copy the replicated snippets to the virtual consolidation layer; perform, by a machine learning model, matching of particular ones of the snippets in the virtual consolidation layer; and produce a search result comprising the matched snippets.

     DETAILED DESCRIPTION 
     Aspects of the present invention relate generally to computer searches and, more particularly, to virtualizing data in natural language searches. According to aspects of the invention, a search query is performed. In embodiments, a virtual consolidation layer is created to store intermediate search results that are then matched using machine learning. In this manner, implementations of the invention produce more comprehensive search results that include data that conventional computer searches would not include. 
     Embodiments, of the invention provide methods and systems to create a virtual layer of a referred element. Methods in accordance with embodiments of the invention link referred content in natural language processing and bring the corpus elements to the virtual layer where it is ready for consumption by machine learning models. In common name (CN) consolidation patterns, embodiments create an ephemeral (temporary) consolidation layer by replicating an unstructured information management architecture (UIMA) classified corpus of snippets that are similar. A natural language query passes through the normal matching procedures and then switches to the ephemeral layer for snippets classified as similar. Embodiments then perform a next level of matching for similarity. 
     Embodiments of the invention provide improved computer searching methods and systems to address the technical problems of missing important data and/or producing an undesirably large number search results. Implementations of the invention provide new functionality enabling the efficient production of relevant search results by creating and using a virtual consolidation layer to store intermediate search results on which matching is performed. 
     It should be understood that, to the extent implementations of the invention collect, store, or employ personal information provided by, or obtained from, individuals such information shall be used in accordance with all applicable laws concerning protection of personal information. Additionally, the collection, storage, and use of such information may be subject to consent of the individual to such activity, for example, through “opt-in” or “opt-out” processes as may be appropriate for the situation and type of information. Storage and use of personal information may be in an appropriately secure manner reflective of the type of information, for example, through various encryption and anonymization techniques for particularly sensitive information. 
     The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention. 
     The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium or media, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire. 
     Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. 
     Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention. 
     Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions. 
     These computer readable program instructions may be provided to a processor of a computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks. 
     The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be accomplished as one step, executed concurrently, substantially concurrently, in a partially or wholly temporally overlapping manner, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions. 
     It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed. 
     Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. 
     Characteristics are as follows: 
     On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service&#39;s provider. 
     Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). 
     Resource pooling: the provider&#39;s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). 
     Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. 
     Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service. 
     Service Models are as follows: 
     Software as a Service (SaaS): the capability provided to the consumer is to use the provider&#39;s applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. 
     Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations. 
     Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls). 
     Deployment Models are as follows: 
     Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises. 
     Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises. 
     Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. 
     Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds). 
     A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes. 
     Referring now to  FIG.  1   , a schematic of an example of a cloud computing node is shown. Cloud computing node  10  is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node  10  is capable of being implemented and/or performing any of the functionality set forth hereinabove. 
     In cloud computing node  10  there is a computer system/server  12 , which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server  12  include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like. 
     Computer system/server  12  may be described in the general context of computer system executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server  12  may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices. 
     As shown in  FIG.  1   , computer system/server  12  in cloud computing node  10  is shown in the form of a general-purpose computing device. The components of computer system/server  12  may include, but are not limited to, one or more processors or processing units  16 , a system memory  28 , and a bus  18  that couples various system components including system memory  28  to processor  16 . 
     Bus  18  represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus. 
     Computer system/server  12  typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server  12 , and it includes both volatile and non-volatile media, removable and non-removable media. 
     System memory  28  can include computer system readable media in the form of volatile memory, such as random access memory (RAM)  30  and/or cache memory  32 . Computer system/server  12  may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system  34  can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus  18  by one or more data media interfaces. As will be further depicted and described below, memory  28  may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention. 
     Program/utility  40 , having a set (at least one) of program modules  42 , may be stored in memory  28  by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules  42  generally carry out the functions and/or methodologies of embodiments of the invention as described herein. 
     Computer system/server  12  may also communicate with one or more external devices  14  such as a keyboard, a pointing device, a display  24 , etc.; one or more devices that enable a user to interact with computer system/server  12 ; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server  12  to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces  22 . Still yet, computer system/server  12  can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter  20 . As depicted, network adapter  20  communicates with the other components of computer system/server  12  via bus  18 . It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server  12 . Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc. 
     Referring now to  FIG.  2   , illustrative cloud computing environment  50  is depicted. As shown, cloud computing environment  50  comprises one or more cloud computing nodes  10  with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone  54 A, desktop computer  54 B, laptop computer  54 C, and/or automobile computer system  54 N may communicate. Nodes  10  may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment  50  to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices  54 A-N shown in  FIG.  2    are intended to be illustrative only and that computing nodes  10  and cloud computing environment  50  can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser). 
     Referring now to  FIG.  3   , a set of functional abstraction layers provided by cloud computing environment  50  ( FIG.  2   ) is shown. It should be understood in advance that the components, layers, and functions shown in  FIG.  3    are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided: 
     Hardware and software layer  60  includes hardware and software components. Examples of hardware components include: mainframes  61 ; RISC (Reduced Instruction Set Computer) architecture based servers  62 ; servers  63 ; blade servers  64 ; storage devices  65 ; and networks and networking components  66 . In some embodiments, software components include network application server software  67  and database software  68 . 
     Virtualization layer  70  provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers  71 ; virtual storage  72 ; virtual networks  73 , including virtual private networks; virtual applications and operating systems  74 ; and virtual clients  75 . 
     In one example, management layer  80  may provide the functions described below. Resource provisioning  81  provides dynamic procurement of computing resources and other resources that are utilized to perform tasks within the cloud computing environment. Metering and Pricing  82  provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may comprise application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User portal  83  provides access to the cloud computing environment for consumers and system administrators. Service level management  84  provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) planning and fulfillment  85  provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA. 
     Workloads layer  90  provides examples of functionality for which the cloud computing environment may be utilized. Examples of workloads and functions which may be provided from this layer include: mapping and navigation  91 ; software development and lifecycle management  92 ; virtual classroom education delivery  93 ; data analytics processing  94 ; transaction processing  95 ; and data virtualization  96 . 
     Implementations of the invention may include a computer system/server  12  of  FIG.  1    in which one or more of the program modules  42  are configured to perform (or cause the computer system/server  12  to perform) one of more functions of the data virtualization  96  of  FIG.  3   . For example, the one or more of the program modules  42  may be configured to: create a virtual consolidation layer; replicate snippets that are the result of a query; copy the replicated snippets to the virtual consolidation layer; perform, by a machine learning model, matching of particular ones of the snippets in the virtual consolidation layer; and produce a search result comprising the matched snippets. 
     Different references to any particular content are created in natural language writing and reading such that different words can be used to reference the same content. There is gap in machine learning models such that they are not able to link this type of content and bring it to a virtual layer of a process where it would be ready for consumption. While regular expression rules-based mechanisms are used for aggregation, there are no algorithms that understand that this content is related to other content. As a result, these regular expression-based mechanisms do not build virtual layers on top of which machine learning models for matching could run. 
     Embodiments of the invention create a virtual layer to hold the results (snippets) of preliminary searches such as, for example, those using unstructured information management architecture (UIMA). Each snippet is a search result in a set of search results. In embodiments, the creation of the virtual layer is through consolidation of natural language snippets which are intra and/or inter documents. A natural language snippet is a snippet that is in natural language. In embodiments, the creation of the virtual layer is through federation of natural language snippets which are intra and/or inter documents. In embodiments, when a user searches for content that is related to a particular subject, the results of the search (often a large amount of data) are brought to the virtual layer so that the results are extensive. In embodiments, correlation of all the data that results from the search happens in the virtual layer. 
     Embodiments provide methods and systems that create a virtual layer of the search results (referred content). Embodiments link the referred content in natural language processing and bring the corpus elements to the virtual layer where it is ready for consumption by machine learning models. 
       FIG.  4    shows a block diagram of an exemplary environment in accordance with aspects of the invention. In embodiments, the environment includes a computer device  100  such as, for example, computer system/server  12  in  FIG.  1   , that communicates over one or more networks  200  such as, for example, cloud computing environment  50  of  FIG.  2   . In embodiments, computer device  100  comprises: a virtualization module  110  comprising, for example, one or more of program modules  42  in  FIG.  1   ; a common name (CN) discovery module  120  comprising, for example, one or more of program modules  42  in  FIG.  1   ; a matching module  130  comprising, for example one or more of program modules  42  in  FIG.  1   ; and a storage device  140  such as, for example, storage system  34  in  FIG.  1   . Computer device  100  may include additional or fewer modules than those shown in  FIG.  4   . In embodiments, separate modules may be integrated into a single module. Additionally, or alternatively, a single module may be implemented as multiple modules. Moreover, the quantity of devices and/or networks in the environment is not limited to what is shown in  FIG.  4   . In practice, the environment may include additional devices and/or networks; fewer devices and/or networks; different devices and/or networks; or differently arranged devices and/or networks than illustrated in  FIG.  4   . 
     In embodiments, virtualization module  110  shown in  FIG.  4    is configured to perform various functions described below, including creating a virtualization layer. In embodiments, CN discovery engine  120  performs searches, as described in more detail below.  FIG.  4    shows two data sources  310 ,  320  that are accessed by CN discovery module  120  to produce search results that virtualization module  110  uses to create the virtualization layer. While two data sources  310 ,  320  are shown in  FIG.  4   , in embodiments, more or fewer data sources are accessed and searched during a search. In embodiments, data sources  310 ,  320  are sources of data such as, for example, databases and/or websites. In embodiments, the virtualization layer is stored in storage device  140 . In embodiments, matching module  130  is configured to perform matching of some of the search results based on, for example, machine learning models to produce, as a final search result, further refined search results. In embodiments, some or all of the search functions described as being performed by CH discovery module  120  are performed by an external search engine  400 , shown in  FIG.  4   . 
       FIG.  5    shows an example of common name (CN) consolidation in accordance with embodiments of the invention. In an exemplary CN consolidation pattern, virtualization module  110  creates a temporary consolidation layer (virtual consolidation layer) by replicating UIMA classified snippets into a corpus of snippets which are identified by CN discovery module  120  as being similar. In embodiments, a consolidation layer is a layer of processing where consolidated intermediate results are stored. In embodiments, this is performed by running a query (for example, a natural language query using natural language processing) and copying the results to the consolidation layer if a similar classification is identified. In embodiments, the query uses analytics based on UIMA. Matching module  130  then performs a next level of matching within the consolidation layer.  FIG.  5    shows an end point manager module  510  which, in embodiments, manages an end point of the corpus of snippets to the consolidation layer.  FIG.  5    shows a CN replicator module  520  which, in embodiments, creates a replica of the corpus of snippets in the consolidation layer.  FIG.  5    shows a CN watchdog module  530  which, in embodiments, monitors changes to the corpus of snippets.  FIG.  5    shows a CN recycler module  540  which, in embodiments, recycles and realigns (refreshes) the corpus of snippets. For example, in embodiments, CN recycler module  540  refreshes the corpus of snippets by updating the search results (adding and/or subtracting snippets) and/or updating the content of one or more snippets as a result of information changes at the source of the one or more snippets.  FIG.  5    shows a consolidation orchestration module  560  which, in embodiments, orchestrates the operations and interactions of CN discovery module  120 , end point manager module  510 , CN replicator module  520 , CN watchdog module  530 , and CN recycler module  540 .
