## Background
FIELD OF THE INVENTION
Embodiments of the invention generally relate to information technology, and, more particularly, to human language translation technology.
BACKGROUND
Translation of documents as a service can be time-consuming and include challenging accuracy and formatting requirements. Accordingly, there exists a need to improve translation services via reducing overall turn-around time and cost, reducing variability in addition to time and cost, and increasing utilization of translators. Specifically, needs exist to more effectively utilize heterogeneity in translators' skills as well as heterogeneity in document complexity within and across documents. Similarly, there also exists a need to improve the skill set of translators and reduce translator boredom and fatigue, thus reducing errors and increasing accuracy.
SUMMARY
In one aspect of the present invention, techniques for translation decomposition and execution are provided. An exemplary computer-implemented method for document translation can include steps of decomposing a document associated with a document translation request into two or more document parts based on meta-data of the document and content of the document, estimating translation complexity between a source language and a target language for each of the two or more document parts, classifying the two or more document parts based on the estimated translation complexity of each part and meta-data corresponding to each part, assigning each of the two or more document parts to a particular individual amongst a set of translators for translation based on the classification of each part and one or more variables associated with the set of translators, assembling each translation output for the two or more document parts to form a final output, and formatting the final output. The same technique can be extended to multiple documents in a translation request. Also, a translation request can additionally include tasks of translation, pre-processing steps (such as format conversion), figure extraction and post-processing steps (such as formatting, verification, etc.).
In another aspect of the invention, an exemplary computer-implemented method for document translation can include steps of classifying each of multiple documents identified in a translation request into two or more classification categories based on the content of each document, and decomposing each of the multiple documents into multiple individual document parts based on the classification category associated with each document. The method can also include measuring complexity of translation between a source language and a target language for each individual document part of each of the multiple documents, assigning each individual document part to a particular individual amongst a set of individuals for translation based on the complexity of translation for each document part and one or more variables of the set of individuals, assembling and formatting the multiple individual document parts of each of the multiple documents, post-translation, into a document collection.
Another aspect of the invention or elements thereof can be implemented in the form of an article of manufacture tangibly embodying computer readable instructions which, when implemented, cause a computer to carry out a plurality of method steps, as described herein.
Furthermore, another aspect of the invention or elements thereof can be implemented in the form of an apparatus including a memory and at least one processor that is coupled to the memory and operative to perform noted method steps. Yet further, another aspect of the invention or elements thereof can be implemented in the form of means for carrying out the method steps described herein, or elements thereof; the means can include hardware module(s) or a combination of hardware and software modules, wherein the software modules are stored in a tangible computer-readable storage medium (or multiple such media).
These and other objects, features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a block diagram illustrating an example embodiment, according to an aspect of the invention;
FIG. 2 is a flow diagram illustrating techniques for document translation, according to an embodiment of the invention; and
FIG. 3 is a system diagram of an exemplary computer system on which at least one embodiment of the invention can be implemented.



DETAILED DESCRIPTION
As described herein, an aspect of the present invention includes machine translation (MT) and computer-based translation tools. At least one embodiment of the invention includes using MT tools interactively to translate, assemble and format a document, as well as review the entire document.
MT tools are useful because there can be large amounts of material that need to be translated, and human translators often cannot feasibly handle the entirety of such material. Also, technical materials can be dense and/or repetitive, potentially leading to fatigue of human translators. Additionally, there can often be a requirement that terminology is used consistently throughout translations, and MT tools can be useful in achieving this objective. The use of computer-based translation tools can also increase the volume and speed of translation throughput. However, as computers do not always produce satisfactory translations, aspects of the invention include providing and implementing interactive MT tools.
Additionally, as detailed herein, at least one embodiment of the invention includes analyzing the complexity of translation relation between source and target languages to determine the extent to which the translation can be performed automatically, and to what extent the translation would be more effectively carried out by a human translator with a particular skill level. By way of example, the complexity of the source language grammar rules and the target language grammar rules can be estimated, and Kullback-Leibler (KL) divergence can be used to provide a measure of the difference of complexity.
Also, an aspect of the invention includes analyzing complexity of a source document during consideration for the translation of documents. For example, a basic letter with non-technical terms can be translated more easily than a technical scientific paper, medical text, complex legal contract, software manual, etc. Documents (that is, documents to be translated) can be classified by complexity. Similarly, parts of a single document (for example, sections, paragraphs, or sentences) can be classified by complexity as well. Besides this classification that may be based on meta-data and service requirements (for example, turn-around time, security/privacy policies), document content can also be used to categorize the document and/or one or more portions thereof. Also, at least one embodiment of the invention can further include compression of documents, for example, beyond a simple word count. Based on compression results and a benchmark, a document or portions thereof can be categorized on a scale from easy to hard.
Further, as described herein, a document can be decomposed into parts or portions based on contextual independence, complexity and/or size of the parts/portions. In at least one embodiment of the invention, dividing the document into contextually independent parts includes generating a graph of a document, where each node is a paragraph (or a section), and there is a link between two nodes if those paragraphs have common keywords. Any standard graph partitioning method can be used to partition the graph into disjoint sets of paragraphs or sections.
As such, entire documents and/or parts of documents, as well as processes (such as translating, formatting, and reviewing) and/or parts of processes can be assigned to different translators in an effort to optimize time and cost parameters (for example, typically reviewers are most expensive, and formatting cost is least expensive). Such partitioned assignments can be based on projected turn-around time (that is, execution time for completing the task), where turn-around time is the sum of translation time, formatting time, and reviewing time. Additionally, the assignments can be based on translator skill and availability, as well as on the processing rate corresponding to the document and/or document part. Further, assignments can also be based on the role of a particular translator in the overall process, where roles can include translator, editor, formatting specialist, reviewer, etc.
Also, in at least one embodiment of the invention, the document and/or portions thereof can be assigned to different translators based additionally on considerations of heterogeneity of document part type for each translator in an effort to, for example, reduce monotony for translators and build the skill levels of translators.
Decomposing and assigning/distributing documents and/or portions of documents to different individuals in a set of translators can also be based on considerations of workload balancing among translators, as well as incorporating multiple translation styles for each document.
At least one embodiment of the invention can additionally include implementation of a pull mode, wherein translators can “pull” or retrieve particular documents and/or particular parts of a document for execution. Pull mode can be effective, for example, when the variance in the translation complexity estimation is large (for example, greater than a pre-determined threshold); that is, when there exists uncertainty with respect to how much effort and/or time is needed to translate a document or a particular portion thereof. Pull mode includes identifying repeated portions within each document and retrieving a translation (if available) for such repeated portions from a memory or database. By way of example, the documents and portions thereof can be stored in an online database, along with corresponding meta-data and categorization information. A translator can retrieve a document or a portion thereof from this database even if the document or portion has not been assigned to him/her if the translator determines that he/she can complete the job more efficiently than otherwise determined.
FIG. 1 is a block diagram illustrating an example embodiment, according to an aspect of the invention. By way of illustration, FIG. 1 depicts translation analysis and decomposition system 102, which includes various components and functions as described below.
As illustrated, function 104 includes identifying documents for translation in a document collection. The complexity of the requested translation between two or more identified languages is measured in step 108, while the collected documents are classified in step 106 based on an identified level of complexity of the document (for example, a simple letter, a technical paper, a legal contract). The classified documents 110 are identified accordingly and split or decomposed into individual parts or portions in step 112. The individual portions 114 of each document can be classified using a level of complexity associated with each individual portion.
Further, step 116 includes identifying repeated portions within each document and retrieving a translation (if available) for such repeated portions from a memory or database. Step 118 includes assigning particular document parts as well as service tasks to various individual translators based on available translation tasks 120 and translator roles 132. In the example embodiment of the invention depicted in FIG. 1, translation tasks 120 considered in step 116 include pre-processing 122, translation 124 and formatting 126. Formatting of documents can include ensuring that correct margins and/or correct fonts are used, as well as ensuring that special characters including language and/or geography specific language, pictures, and/or tables are laid out correctly, etc. Preprocessing can include tasks such as converting to a particular type of document (DOC to PDF, etc.), extracting figures/tables, determining skill level for a group of available translators, and understanding translation requirements.
Additionally, translator roles 132 include a skilled translator with domain knowledge 134, a translator 136, a formatter 138 and a validator 140. By way of example, the difference between skilled translator 134 and translator 136 can include the difference in corresponding skill set with respect to the translation task in hand.
Once the document parts and service tasks have been assigned in step 118, step 142 includes assembling the translated portions and documents into the document collection. This can additionally include input and/or interaction with validation 128 and post-processing 130 tasks. Validation can include checking whether the translation is correct, and post-processing can include confirming that the document meets any requirements, and performing any clean-up actions (if required).
FIG. 2 is a flow diagram illustrating techniques for document translation, according to an embodiment of the present invention. Step 202 includes decomposing a document associated with a document translation request into two or more document parts based on meta-data of the document and content of the document. Content of the document can include, for example, contextually independent portions of the document, as well as size of the document. Also, service requirements associated with the translation request can include, for example, completion time as well as a security and/or privacy policy.
Step 204 includes estimating translation complexity between a source language and a target language. Estimating translation complexity can include determining the extent to which the translation request can be executed automatically, and the extent to which the translation request is to be executed by an individual. Also, estimating translation complexity can include analyzing complexity of grammar rules for the source language and the target language, and using a divergence measure to quantify a difference in the complexity of grammar rules between the source language and the target language. Further, estimating translation complexity can include estimating a processing rate corresponding to each document part.
Step 206 includes assigning each of the two or more document parts to a particular individual amongst a set of translators for translation. As also described herein, translation execution parameters can include, for example, execution time and/or execution cost. Additionally, variables of the set of individuals can include, for example, skill and/or availability of each individual in the set of individuals/translators, as well as heterogeneity of document part type assigned to each individual. Variables associated with the set of translators can also include, for example, workload balance across the set of translators.
Additionally, the techniques depicted in FIG. 2 can also include classifying the two or more document parts based on complexity of each part and meta-data corresponding to each part. Further at least one embodiment of the invention includes assembling each translation output for the two or more document parts to form a final output, and formatting the final output. Also, as detailed herein, each of the steps depicted in FIG. 2, in at least one embodiment of the invention, is carried out in accordance with one or more requirements of the document translation request and one or more variables associated with the set of translators. Requirements of the document translation request can include turn-around time as well as cost.
Further, the techniques depicted in FIG. 2 can include assigning each of one or more translation tasks associated with the translation request to a particular individual amongst the set of individuals/translators to satisfy the one or more requirements of the document translation request and the one or more variables associated with the set of translators. Additionally, as detailed herein, at least one embodiment of the invention includes enabling an individual to manually retrieve a particular document part for execution of a task associated with the document translation request.
The techniques depicted in FIG. 2 can also, as described herein, include providing a system, wherein the system includes distinct software modules, each of the distinct software modules being embodied on a tangible computer-readable recordable storage medium. All of the modules (or any subset thereof) can be on the same medium, or each can be on a different medium, for example. The modules can include any or all of the components shown in the figures and/or described herein. In an aspect of the invention, the modules can run, for example, on a hardware processor. The method steps can then be carried out using the distinct software modules of the system, as described above, executing on a hardware processor.

19. The system of claim 18, wherein said formatting comprises using one or more pre-determined margins, one or more pre-determined fonts, one or more pre-determined special characters, one or more pre-determined pictures and/or one or more pre-determined tables.

20. A method for document translation, the method comprising steps of:
classifying each of multiple documents identified in a translation request into two or more classification categories based on the content of each document;
decomposing each of the multiple documents into multiple individual document parts based on the classification category associated with each document;
measuring complexity of translation between a source language and a target language for each individual document part of each of the multiple documents, wherein said measuring the complexity of translation comprises (i) computing a divergence measure to quantify a difference in complexity of one or more grammar rules associated with the source language and one or more grammar rules associated with the target language, and (ii) estimating a processing rate for each of the multiple document parts;
identifying one or more of the document parts comprising a variance in the translation complexity estimation that is greater than a pre-determined threshold;
identifying one or more repeated portions of text within said identified document parts;
retrieving a stored translation for each of said repeated portions from a database;
assigning each respective one of the remaining document parts to one of (i) an automated machine translation module and (ii) a distinct individual amongst a set of multiple human translators for translation such that the document translation request is executed by a combination of the automated machine translation module and one or more of the multiple human translators, and wherein said assigning is based on:
(i) the complexity of translation for each document part,
(ii) required execution time for completing the document translation request, and
(iii) multiple variables of the set of multiple individuals comprising at least translation skill level of each of the multiple human translators and availability of each of the multiple human translators; and

assembling and formatting (i) the stored translation for each of said repeated portions of text within the identified document parts, and (ii) each translation output for the remaining document parts, post-translation, into a final document collection;
wherein the steps are carried out by at least one computer device.
