Abstract: An approach is provided in which a knowledge manager detects an annotation error while attempting to annotate a document and, as such, segments the document into multiple document segments. The knowledge manager then detects another annotation error while attempting to annotate the multiple document segments, resulting in a set of unannotated document segments. In turn, the knowledge manager generates a notification that identifies the set of unannotated document segments.

Abstract: Cognitive medical treatment recommendation mechanisms are provided. The mechanisms ingest a corpus of medical treatment content that comprises drug-to-drug interaction information. The mechanisms generate a set of drug interaction insight data structures and an initial set of candidate treatments for a medical condition of a patient based on an analysis of an electronic medical record associated with the patient. The mechanisms rank candidate treatments in the initial set of candidate treatments based on the set of drug interaction insight data structures to generate a final set of candidate treatments, where the ranking reduces rankings of candidate treatments in which drug interactions are identified in the set of drug interaction insight data structures. The mechanisms output a treatment recommendation based on the final set of candidate treatments.

Abstract: A recommendation engine for works of literature uses patterns of flow and element similarities for scoring a first user-rated work of literature against one or more recommendation candidate works of literature. Cluster models are created using meta-data modeling the works of literature, the meta-data having literary element categories and instances within each category. Each instance is described by an index value (position in the literature) and significance value (e.g. weight or significance). Cluster finding process(es) invoked for each instance in each category find Similarity Concept clusters and Consistency Trend clusters, which are recorded into the cluster models representing each work of literature. The cluster model can be printed or displayed so that a user can visually understand the ebb and flow of each literary element in the literature, and may be digitally compared to other cluster models of other works of literature for potential recommendation to a user.

Abstract: The program directs a computer processor to resolve an anaphor in electronic natural language text. The program detects a plurality of entities and an anaphor in a span of parsed natural language text comprising one or more sentences, and extracts pairs of related entities based on domain knowledge. The program constructs a set of tuples, wherein each tuple is a data type comprising an anaphor, an antecedent entity (AE) appearing before the anaphor in the span of parsed natural language text, and an entity (E) appearing after the anaphor in the span of parsed natural language text, wherein the anaphor refers to the AE and relates the AE to the E. The program resolves the anaphor by determining which entity in the plurality of entities the anaphor references, using the constructed set of tuples, and selecting an AE among one or more candidate AEs.

Abstract: Curating high-quality ground truth is an important but difficult part of training a cognitive system. The invention greatly simplifies this process by determining the value that particular training data has in improving existing ground truth. Candidate training data of different types (text, audio, images) is extracted from an interaction log, and each entry is analyzed to arrive at a training value score. The analysis generates multiple component scores which are combined for the final score. The component scores may include a per-feature variability score, a cross-feature variability score, and an accuracy score. A set of the unverified entries may be presented to a user based on the training value scores, and the user can select which of the entries in the set should be included as new ground truths. The ground truths can then be updated by adding the selected entries.
