The disclosure relates to information retrieval and includes a preprocessing stage and a retrieval stage. The preprocessing stage includes ingesting data in a semantic manner that incorporates domain expert knowledge and that retains contextual information. The ingested data or objects are chunked and chunk embeddings are generated. A knowledge graph is created to hierarchically represent each of the objects. During the retrieval stage, the top k embeddings closest to an embedding of a query are used to identify the semantic cells and metadata cells of a document corresponding to the top k embeddings. This generates a return object that is used an input for content generation.

Semantic segmentation of data for information retrieval

One example method includes enabling a user to define a query that comprises a hybrid search syntax (HSS), and the HSS is in the form of a single string that comprises a lexical component and a semantic component, receiving the query from the user, parsing the lexical component and the semantic component into respective groups of one or more sub-components, performing a lexical search based on the sub-components of the lexical component, and performing a semantic search based on the sub-components of the semantic component, ranking, separately from each other, results of the lexical search and results of the semantic search, combining the results of the lexical search and the results of the semantic search to create aggregate results, and re-ranking the aggregate results.
