## Title
Text analysis on unstructured text to identify a high level of intensity of negative thoughts or beliefs

## Abstract

A method, a processing device, and a computer program product are provided. Via at least one processing device, each text file is selected from a collection of text files, wherein the collection of text files has an intensity with respect to negative sentiment toward a common issue. At least one profile algorithm is performed, each calculating a corresponding profile score for that text file. At least one corresponding profile score of the text files of the collection are combined to produce an aggregated profile score for each of at least one profile algorithm. The aggregated profile score of each of the at least one profile algorithm for the collection is stored. A signature for the collection of text files includes the aggregated profile score of each of the at least one profile algorithm for the collection.

## Background
BACKGROUND
Present invention embodiments are related to systems and methods for analyzing unstructured text to identify a high level of intensity of negative sentiment, thoughts or beliefs. In particular, present invention embodiments are related to performing training on collections of text files, each of the collections being authored by a respective author and having a respective level of intensity of negative thoughts or negative beliefs, to produce at least one aggregated score and comparing the at least one aggregated score to at least one profile score of a text file for analysis to determine a collection that is closest to the text file for analysis.
Often, after an occurrence of a negative event, information authored by an initiator of the negative event is found on a computer network such as, for example, the Internet or other network, that, in hindsight, appear to be obvious clues that the negative event was about to happen. For example, after an occurrence of several recent negative events, postings on websites were found that were authored by initiators of the negative events and would lead one to believe that the recent negative events were about to occur. Since these clues are not truly discovered, no intervention is initiated to prevent negative events.
SUMMARY
According to embodiments of the present invention, a computer-implemented method, a processing device, and a computer program product are provided. Embodiments may be implemented by at least one processing device. Each text file from a collection of text files may be selected via at least one processing device. The collection of text files have an intensity with respect to negative sentiment toward a common issue. At least one profile algorithm is performed, each calculating a corresponding profile score for that text file. At least one corresponding profile score of the text files of the collection are combined to produce an aggregated profile score for each of at least one profile algorithm for the collection. The aggregated profile score of each of the at least one profile algorithm for the collection may then be stored. A signature for the collection of text files includes the aggregated profile score for each of the at least one profile algorithm for the collection.
In another aspect of the embodiments of the present invention, a desired text file may be selected for analysis. At least one profile algorithm may be performed, with respect to the desired text file, to calculate a corresponding profile score for each profile algorithm. The profile score for the at least one profile algorithm may be stored. Signatures of each of the collection of text files may be compared to a signature of a desired text file. The signature of the desired text file includes the profile scores, with respect to the desired text file, for each of the profile algorithms. An indication of collections having signatures within a threshold distance of the signature of the desired text file may be provided, and a user configurable action may be performed when at least one collection has a signature within the threshold distance of the desired text file.

DETAILED DESCRIPTION
With reference now to FIG. 1, an example environment 100 for implementation of embodiments is shown. Example environment 100 may include one or more servers 102, a network 104, and one or more databases, which may include collections of unstructured textual input 106 and one or more textual inputs for analysis 108. Although FIG. 1 shows two databases, other embodiments may include collections of unstructured textual input and one or more textual inputs for analysis in a single database or this data may be included in a different number of databases.
Network 104 may be implemented by any number of any suitable communications media (e.g., wide area network (WAN), local area network (LAN), Internet, Intranet, etc.). In some embodiments, server(s) 102, collections of textual input 106 and one or more textual inputs for analysis 108 may be local to each other and may communicate with each other via any appropriate local communication medium (e.g., local area network (LAN), hardwire, wireless link, Intranet, etc.). In other embodiments, server(s) 102, collections of textual input 106 and one or more textual inputs for analysis 108 may be remotely located from each other and may communicate with each other via a WAN, Internet, etc.
In a training phase, one or more server(s) 102 may have access to collections of textual input 106, each of which may be authored by a different respective author. Within each of the collections, each text file has a same or similar level of intensity for negative sentiments, thoughts or beliefs with respect to a common issue and relative to common social standards and attitudes. One or more servers 102 may be trained, using multiple collections of textual input, each with a varying intensity level of negative sentiment to recognize each of multiple levels of the intensity.
After completion of the training phase, an unstructured textual input may be analyzed using a same group of algorithms that were used to train the one or more servers. The one or more servers may indicate a level of intensity of the analyzed textual input based on a distance between signatures of each of the collections with varying intensity levels and a signature of the analyzed text. In some embodiments, the distance may be a Euclidean distance.
Referring now to FIG. 2, a schematic of an example processing device 210 is shown, which may implement a server of server(s) 102. Processing device 210 is only one example of a suitable processing device for the environment of FIG. 1 and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, processing device 210 is capable of being implemented and/or performing any of the functionality set forth herein.
In processing device 210, there is a computer system 212 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 212 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 212 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 212 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. 2, computer system 212 is shown in the form of a general-purpose computing device. Components of computer system 212 may include, but are not limited to, one or more processors or processing units 216, a system memory 228, and a bus 218 that couples various system components including system memory 228 to one or more processors 216.
Bus 218 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 212 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system 212, and includes both volatile and non-volatile media, and removable and non-removable media.
System memory 228 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 230 and/or cache memory 232. Computer system 212 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 234 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 218 by one or more data media interfaces. As will be further depicted and described below, memory 228 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 240, having a set (at least one) of program modules 242, may be stored in memory 228 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, the one or more application programs, the other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules 242 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.
Computer system 212 may also communicate with one or more external devices 214 such as a keyboard, a pointing device, a display 224, etc.; one or more devices that enable a user to interact with computer system 212; and/or any devices (e.g., network card, modem, etc.) that enable computer system 212 to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces 222. Still yet, computer system 212 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 220. As depicted, network adapter 220 communicates with the other components of computer system 212 via bus 218. It should be understood that, although not shown, other hardware and/or software components could be used in conjunction with computer system 212. 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.
FIG. 3 is a flowchart that illustrates example processing in a training phase of an embodiment. The process may begin with one or more servers 102 selecting access to a collection of unstructured text files 106 (act 302), which may be local or remote from one or more servers 102. One or more servers 102 may then select a first unstructured text file of the selected collection of unstructured text files 106 (act 304). Each collection of unstructured text files may be authored by a same respective author and may have a same or similar respective level of intensity with respect to negative sentiments, thoughts, or beliefs for a common issue relative to common social standards and attitudes. Authors of the unstructured text files and the levels of intensity may vary from collection to collection. At least some of the authors, whose postings have a high level of intensity, are known to have initiated a negative event with undesirable impact in accordance with their expressed negative sentiments, thoughts or beliefs.
Returning to FIG. 3, a first profile algorithm may be selected (act 306). Each profile algorithm calculates a profile score for an unstructured text file being analyzed. In some embodiments, there may be a number of profile algorithms. The number of profile algorithms may include, but not be limited to, calculating a profile score based on: certain keywords appearing in the text; certain keywords and frequency of use of the keywords; certain keywords appearing in all uppercase characters; words appearing in a font color that is different from a font color used in most of the unstructured text file; appearance of multiple contiguous exclamation points; frequency of appearance of repeated phrases; etc.
One industry standard for context analytics, which may be used in various embodiments, is Unstructured Information Management Architecture (UIMA). UIMA is an architecture that includes software systems for analyzing large volumes of unstructured information in order to discover knowledge that is relevant to an end user. For example, a UIMA application may process text and identify entities, such as persons, places, organizations, or relations such as works-for or located-at. A UIMA pipeline is a list of individual stages, or annotators, which are run serially. When a document is processed by the UIMA pipeline, a first annotator stage may create annotations covering sections of text. When the first stage is completed, the second annotator stage may then process the text. Each subsequent stage may read annotations created by earlier stages and may add or modify the annotations, thus building up a more complex analysis of contents of the document. The annotations could be for an entire document, a paragraph or sentence, a token or an annotation that one can define by creating a custom dictionary or a parsing rule including, but not limited to, a city, particular keywords, punctuation and font color.
Returning to the flowchart of FIG. 3, profile scoring of the unstructured text file is performed according to the profile algorithm (act 308). One or more servers 102 may then store the profile score (e.g., quantity/frequency of . . . , etc.) for the profile algorithm (act 310). One or more servers 102 may determine whether another profile algorithm is to be performed with respect to the unstructured text file (act 312). If so, then a next profile algorithm may be selected (act 314) and acts 308-312 may be repeated.
If, during act 312, a determination is made that no additional profile algorithms are to be performed then a determination is made regarding whether there are additional unstructured text files within the collection (act 316). If there are additional unstructured text files within the collection, then a next unstructured text file of the collection may be selected (act 326) and acts 306-316 may be repeated.
If, during act 316, a determination is made that there are no more unstructured text files to process within the collection, then corresponding profile scores from the profile algorithms for each of the unstructured text files may be combined to produce corresponding aggregated profile scores per profile algorithm for the collection (act 318). In one embodiment, an aggregated profile score may be an average of corresponding profile scores, a mean value of corresponding profile scores, or another value based on the corresponding profile scores for a collection. The aggregated profile scores associated with each of the profile algorithms may be stored with respect to the collection (act 320). A collection of aggregated profile scores for each collection is a corresponding signature for a respective collection.
Next, one or more servers 102 may determine whether any additional collections of unstructured text files exist (act 322). If one or more additional collections exist, then one or more servers 102 may select a next collection of unstructured text files for processing (act 324) and acts 304-322 may be repeated.
If, during act 322, a determination is made that no additional collections remain to be processed, then the process may be complete.
FIG. 4 is a flowchart that illustrates example processing with respect to unstructured text to be analyzed and categorized during a runtime phase. The process may begin with selecting an unstructured text file for analysis and categorization (act 402). Next one or more servers 102 may select a first profile algorithm for calculating a profile score of the selected unstructured text file (act 404). Any profile algorithms performed with respect to the selected unstructured text file were also used during the training phase to process the unstructured text files of the collections. One or more servers 102 may then calculate a profile score with respect to the selected unstructured text file (act 406). The profile score may then be stored with respect to the unstructured text file (act 408). One or more servers may then determine whether another profile algorithm is to be performed with respect to the unstructured text file (act 410). If another profile algorithm is to be performed, then a next profile algorithm may be selected and acts 406-410 may be repeated.
If, during act 410, a determination is made that there are no additional profile algorithms to perform, a signature of the unstructured text file is constructed from the profile scores calculated for corresponding profile algorithms performed with respect to the unstructured text file, and used for analysis and categorization. The signature of the unstructured text file may be compared to respective signatures of each of the collections processed during the training phase (act 414).
During the comparing, a distance may be calculated between the signature of the unstructured text file and the signature of each of the collections. A determination may be made regarding whether the calculated distance between the signature of the unstructured text file and any of the collections is less than or equal to a threshold, which may be configurable via a user interface such as, for example a graphical user interface (GUI) or other type of interface (act 416). If the calculated distance between the signature of the unstructured text file and the signature of any of the collections is less than or equal to the threshold, information may be provided regarding a collection or collections within the threshold and a configurable action may be performed (act 418). The information may be provided in any one of a number of ways including, but not limited to, being displayed on a display screen, printed on a printer, emailed or texted to a user, and being provided via a speaker.
If, during act 416, the calculated distance between the signature of the unstructured text file and the signature of each of the collections is not less than or equal to the threshold, then an indication may be provided regarding no collection being within the threshold of the signature of the unstructured text file.
In some embodiments, the calculated distance may be a Euclidean distance between the signature of a collection and the signature of the unstructured text file being analyzed and categorized. In Euclidean space, n, Euclidean distance is defined as the square root of the sums of the squared differences of each of the corresponding profile scores, i.e. √{square root over (Σi=1n|Pi(collection)−pi(unstructured text)|2)}, where Pi(collection) is the ith aggregated profile score for a collection, pi(unstructured text) is the ith profile score for the unstructured text to be analyzed and categorized and n is a number of profile algorithms.
As mentioned above, the user may configure one or more actions to be taken when a signature of one or more collections has a distance, with respect to a signature of an unstructured textual document, that is within the threshold distance. FIGS. 5-8 illustrate an exemplary user interface for configuring the one or more actions to be taken.
FIG. 5 shows four example actions which the user may select to be taken when a signature of a collection is determined to be within a threshold distance of a signature of an unstructured text file being analyzed. The actions may include but not be limited to: contact local police; send email; send text message; and call phone number.
FIG. 6 shows that when the user selects “SEND EMAIL”, the user is prompted to enter one or more email addresses. To which a message may be sent.
FIG. 7 shows that when the user selects “SEND TEXT MESSAGE”, the user is prompted to enter one or more phone numbers to which a text message may be sent.
FIG. 8 shows that when the user selects “CALL PHONE NUMBER”, the user may be prompted to enter one or more phone numbers which will be called with a message indicating that an unstructured text document was found to have a signature within a threshold distance of the signature of at least one collection.
