Abstract: Provided are techniques for dynamic fact contextualization in support of AI model development. A template from a plurality of templates is selected, where the template includes definitions for identifying facts. The facts are retrieved from a facts repository based on the definitions. It is determined that that the facts are valid based on one or more policies. A FactSheet is generated using the template and the facts. A machine learning model is used to identify one or more deficient facts from the FactSheet. The FactSheet is displayed in a preview with the one or more deficient facts. One or more facts corresponding to the one or more deficient facts are located. The FactSheet is updated to correct the one or more deficient facts with the corresponding facts.

Abstract: Several aspects for optimizing unstructured document analysis comprise operating a document system, where the document system comprises a plurality of documents comprising unstructured content and a full-text index; receiving a request to identify documents comprising a type of data elements; selecting a sample out of the plurality of documents; determining data elements of the type in the sample of documents; determining an indicator context expression for the type of data elements out of the determined data elements of the type; determining a query for searching, using a search engine, the full-text index using the indicator context expression; and determining the documents in the document system being compliant to the determined query.

Abstract: The present disclosure relates to a method of metadata enrichment using an enrichment comprising multiple steps. The method comprises: determining for an input data asset a metadata value descriptive of the input data asset. Characteristics of the metadata value of the input data asset may be determined. At least one informativeness score of the metadata value of the input data asset may be computed using the determined characteristics. An execution of the enrichment step may be skipped in case an input characteristic of the enrichment step is not part of the determined characteristics. In case the input characteristic of the enrichment step is part of the determined characteristics, the enrichment step may be adapted and executed or the enrichment step may be executed without adaptation. Labels resulting from the executed enrichment steps may be combined for providing one or more labels of the data asset.

Abstract: A method for providing one or more random sample documents from a corpus of documents using a search engine is provided. The providing of each of the random sample documents comprises selecting randomly a time window from a set of time windows. A search query is sent to the search engine defining a search for documents of the corpus with time-stamps within the time window defined by the randomly selected time window. In response to the sending of the search query, a search result is receiving from the search engine. The search result comprises a set of the documents of the corpus with time-stamps within the time window. One of the documents comprised by the received set of documents is then selected randomly.

Abstract: Described are techniques for a re-analysis of assignments of terms to assets. The techniques include detecting a change in a term ontology comprising a plurality of terms, and determining at least one selected from a group consisting of: a domain feature change vector (DFCV) for a domain of the term ontology affected by the change, and a term feature change vector (TFCV) for the term affected by the change. The techniques further include identifying assets for the re-analysis of the assignments of terms, wherein each of the identified assets is associated with an impact score value based on the DFCV and/or the TFCV, and performing the re-analysis of the assignments of terms for the identified assets ordered by the impact score value.

Abstract: Techniques are described relating to unstructured document processing. An associated computer-implemented method includes identifying a plurality of deduplicated data blocks associated with a collection of unstructured documents. The method further includes sorting the plurality of deduplicated data blocks in descending order based upon at least one block frequency metric, selecting a highest sorted unprocessed deduplicated data block, applying text analytics to the selected deduplicated data block, and applying at least one result of the text analytics to any document among the collection of unstructured documents including the selected deduplicated data block. The method is terminated responsive to satisfaction of at least one stopping condition.

Abstract: A method for providing one or more random sample documents from a corpus of documents using a search engine is provided. The providing of each of the random sample documents comprises selecting randomly a time window from a set of time windows. A search query is sent to the search engine defining a search for documents of the corpus with time-stamps within the time window defined by the randomly selected time window. In response to the sending of the search query, a search result is receiving from the search engine. The search result comprises a set of the documents of the corpus with time-stamps within the time window. One of the documents comprised by the received set of documents is then selected randomly.

Embodiments of the present invention can extract of structured information for unstructured document analysis. Embodiments of the present invention can extract structured information for unstructured document analysis by identifying tables and columns of a database that correspond to business terms of a business glossary. Embodiments of the present invention can then receive a specification of business terms of interest for recognizing in an unstructured document. Embodiments of the present invention can then generate an analysis module based on the identified tables and columns that enables to identify or recognize attribute values of attributes of the tables and columns. Embodiments of the present invention can then use the analysis module for automatic extraction of values of at least part of the attributes from the unstructured document based on the specification of business terms of interest.

Abstract: Providing access to media data shared by multiple users. A predefined edge weight is assigned to each edge of a linked data structure based on a dependency category of the edge. A first access rating value is assigned to each node. A rating residue value is calculated as the difference between the two first access rating values of the nodes connected by each edge. The data structure is traversed from a seed node, and for each edge traversed, calculating a second access rating value using an edge weight value and the first access rating value. Repeating until the rating residue values meet a predefined convergence criterion. The nodes having access rating values meeting a predefined data removal criterion are selected from the nodes of the linked data structure. The data entities corresponding to the selected nodes are then removed.

Abstract: Provided are techniques for creating an inverted index for features of a set of data elements, wherein each of the data elements is represented by a vector of features, wherein the inverted index, when queried with a feature, outputs one or more data elements containing the feature. The features of the set of data elements are ranked. For each feature in the ranked list, the inverted index is queried for data elements having the feature and not having any previously selected feature and a cluster of the data elements is created based on results returned in response to the query.
