Abstract: In an approach to determining an introduction of a user in a meeting, one or more computer processors retrieve a document containing information associated with a user, wherein the document includes one or more fragments describing the user. The one or more computer processors determine an audience of a meeting associated with the user. The one or more computer processors determine a description of the meeting. The one or more computer processors prioritize one or more of the one or more fragments, based, at least in part, on the audience of the meeting and on the description of the meeting. The one or more computer processors select one or more of the one or more fragments for the introduction of the user in the meeting, based, at least in part, on the prioritization of the one or more fragments.

Abstract: A search engine system provides search results that are ranked according to a measure of the trust associated with entities that have provided labels for the documents in the search results. A search engine receives a query and selects documents relevant to the query. The search engine also determines labels associated with selected documents, and the trust ranks of the entities that provided the labels. The trust ranks are used to determine trust factors for the respective documents. The trust factors are used to adjust information retrieval scores of the documents. The search results are then ranked based on the adjusted information retrieval scores.

Abstract: A method and system for managing a media advertising enterprise including process and workflow capabilities for enterprise data matching. An EDM (Enterprise Data Management) module can be configured to include a set of rules at an enterprise level to manage disparate and disconnected records associated with an entity. A number of unmatched and enterprise entities that matches with respect to an active entity can be returned based on a fuzzy logic. A matching process can then be performed to accurately match the active entity and the unmatched entities with respect to a parent enterprise entity. The unmatched entity can be put on hold if additional information is required for performing a right match after assigning the parent enterprise entity. A note can also be added in order to place the unmatched entity on hold. Such an optimization mechanism can interactively manage and report records at the enterprise level in a simple and efficient manner.

Abstract: Data may be retrieved from databases using various types of code, functions and programs. To insure that the code, functions and programs comply with privacy requirements and regulations, the code and programs may be audited. In one example, an activity log may be queried to identify code that was executed to retrieve and display database information. A system may then determine whether an unauthorized entity was able to retrieve and/or view the database information. If so, the code or program may be labeled as non-compliant. Alternatively or additionally, a system may parse data retrieval code to determine whether privacy protection code is included therein. If not, the code may be deemed non-compliant. Reports may be generated identifying the non-compliant data retrieval code or function and, in some arrangements, specifying compliance statistics.

Abstract: A method and system for expanding a template tree. A received search request includes (i) a search query and (ii) path information specifying at least one path of data nodes of the template tree. The template tree is a hierarchically organized data structure of data nodes. Each specified path in the path information includes a sequence of data nodes of the template tree. The data nodes in each sequence in each specified path are traversed. Each traversed data node that does not have a child node in the template tree is expanded to form in the template tree one or more child nodes corresponding to each expanded data node. Any other data node of the template tree is not expanded. Each formed one or more child nodes is instantiated with data values by retrieving the data values, in accordance with the search query, from at least one data source.

Abstract: The ranking quality of a ranked list may be evaluated. In an example embodiment, a method is implemented by a system to access log data, ascertain which entries of a ranked list are skipped, and determine a ranking quality metric from the skipped entries. More specifically, log data that reflects user interactions with a ranked list having multiple entries is accessed. The user interactions include at least indications of which of the multiple entries are selected entries. It is ascertained which entries of the multiple entries of the ranked list are skipped entries based on the selected entries. The ranking quality metric for the ranked list is determined responsive to the skipped entries.

Abstract: Mechanisms are provided for performing efficient compression and deduplication of data segments. Compression algorithms are learning algorithms that perform better when data segments are large. Deduplication algorithms, however, perform better when data segments are small, as more duplicate small segments are likely to exist. As an optimizer is processing and storing data segments, the optimizer applies the same compression context to compress multiple individual deduplicated data segments as though they are one segment. By compressing deduplicated data segments together within the same context, data reduction can be improved for both deduplication and compression. Mechanisms are applied to compensate for possible performance degradation.
