Abstract: A method for obtaining and providing search suggestions using entity co-occurrence is disclosed. The method may be employed in any search system that may include at least one search engine, one or more databases including entity co-occurrence knowledge and trends co-occurrence knowledge. The method may extract and disambiguate entities from search queries by using an entity and trends co-occurrence knowledge in one or more database. Subsequently, a list of search suggestion may be provided by each database, then by comparing the score of each search suggestion, a new list of suggestion may be built based on the individual and/or overall score of each search suggestion. Based on the user's selection of the suggestions, the trends co-occurrence knowledgebase can be updated, providing a means of on-the-fly learning, which improves the search relevancy and accuracy.

Abstract: A system and method for detecting events based on input data from a plurality of sources. The system may receive input from a plurality of sources containing information about possible events. A method for event detection involves pre-processing and normalizing a data input from a plurality of sources, extracting and disambiguating events and entities, associate event and entities, correlate events and entities associated from a data input to results from a different data sources to determine if an event has occurred, and store the detected events in a data storage.

Abstract: A method for disambiguating features in unstructured text is provided. The disclosed method may not require pre-existing links to be present. The method for disambiguating features in unstructured text may use co-occurring features derived from both the source document and a large document corpus. The disclosed method may include multiple modules, including a linking module for linking the derived features from the source document to the co-occurring features of an existing knowledge base. The disclosed method for disambiguating features may allow identifying unique entities from a knowledge base that includes entities with a unique set of co-occurring features, which in turn may allow for increased precision in knowledge discovery and search results, employing advanced analytical methods over a massive corpus, employing a combination of entities, co-occurring entities, topic IDs, and other derived features.

Abstract: A computer system and method for automated discovery of topic relatedness are disclosed. According to an embodiment, topics within documents from a corpus may be discovered by applying multiple topic identification (ID) models, such as multi-component latent Dirichlet allocation (MC-LDA) or similar methods. Each topic model may differ in a number of topics. Discovered topics may be linked to the associated document. Relatedness between discovered topics may be determined by analyzing co-occurring topic IDs from the different models, assigning topic relatedness scores, where related topics may be used for matching/linking a feature of interest. The disclosed method may have an increased disambiguation precision, and may allow the matching and linking of documents using the discovered relationships.

Abstract: A method for generating search suggestions by using fuzzy-score matching and entity co-occurrence in a knowledge base is disclosed. Embodiments of the method may be employed in any search system that may include an entity extraction computer module that may perform partial entity extractions from provided search queries, a fuzzy-score matching computer module that may generate algorithms based on the type of entity extracted and perform a search against an entity co-occurrence knowledge base. The entity co-occurrence knowledge base, which may include a repository where entities may be indexed as entities to entities, entities to topics, or entities to facts among others, may return fast and accurate suggestions to the user to complete the search query. The suggestions may include alternates to the partial query provided by the user that may enhance and save time when performing searches.

Abstract: A system for building a knowledge base of co-occurring features extracted from a document corpus is disclosed. The method includes a plurality of feature extraction software modules that may extract different features from each document in the corpus. The system may include a knowledge base aggregator module that may keep count of the co-occurrences of features in the different documents of a corpus and determine appropriate co-occurrences to store in a knowledge base.

Abstract: A system and method for detecting and summarizing events based on data feeds from a plurality of sources. Such sources may include social media networks, text messages, news feeds among others. The system may receive raw information from such sources containing data related with possible events. Method for event detection may include pre-processing and normalizing data input from any source registered, this may also include; extracting and disambiguating events and entities, associate event and entities, correlate events and entities associated from a data input which results from a different data source, for validating/verifying an event. Subsequently, the validated/verified event may be stored in a local data storage and/or in a web-server.

Abstract: Methods for providing in-loop validation of disambiguated features are disclosed. The disclosed methods may include disambiguating features in unstructured text that may use co-occurring features derived from both the source document and a large document corpus. The disambiguating systems may include multiple modules, including a linking on-the-fly module for linking the derived features from the source document to the co-occurring features of an existing knowledge base.

The disclosed method may use validation to provide input to the system for disambiguating features.

Abstract: A system and method for extracting facts from unstructured text files are disclosed. Embodiments of the disclosed system and method may receive a text file as input and perform extraction and disambiguation of entities, as well as extract topics and facts. The facts are extracted by comparing against a fact template store and associating facts with events or topics. The extracted facts are stored in a data store.
