13 results about "Text database" patented technology

A text database is a system that maintains a (usually large) text collection and provides fast and accurate access to it. These two goals are relatively orthogonal, and both are critical to profit from the text collection. Traditional database technologies are not well suited to handle text databases.

Auxiliary diagnosis result and reference prescription generation method and device, medium and computer equipment

This invention discloses a method and system for generating auxiliary diagnostic results and reference prescriptions. First, a medical record database and a treatment strategy database are constructed and stored in a vector database and a text retrieval database, respectively. For a target medical record, vectorization and textualization are performed. Then, candidate medical records and treatment strategies are retrieved from the medical record vector database, medical record text database, treatment strategy vector database, and treatment strategy text database via four channels. Subsequently, the RRF algorithm is used to fuse and sort the vector and text channels, and the candidate results are further refined based on a pre-trained semantic ranking model to obtain a small number of reference medical records and treatment strategies highly relevant to the current condition. Finally, prompt words are constructed by combining the target medical record, reference medical records, and treatment strategies to generate candidate results such as TCM diagnosis, TCM syndrome type, Western medicine diagnosis, and TCM prescriptions, serving as auxiliary references for doctors' clinical decision-making. This significantly improves the accuracy, interpretability, and efficiency of intelligent assisted diagnosis and treatment.

A large model hallucination mitigation method based on multi-agent cooperation and dynamic state tracking

PendingCN122334458AText databaseTheoretical computer science
This invention discloses a method for mitigating hallucinations in large-scale narratives based on multi-agent collaboration and dynamic state tracking. The method includes: generating an event graph composed of multiple atomic events using an outline agent; mapping these atomic events from an event occurrence time series to a text narrative time series using an orchestration agent; constructing a non-linear narrative outline; retrieving historical fragments related to the semantics and sentiment of the current chapter from the generated historical text; generating the text content of the current chapter using a writing agent; performing real-time logical consistency checks on the content during generation; triggering a correction mechanism when entity state changes in the generated content violate preset state transition rules; and parsing the entity state changes after the current chapter is finalized, updating the global state table and historical text database. This invention effectively mitigates hallucinations in long narratives, significantly improving the logical rigor and long-term coherence of the plot development while maintaining the literary quality of the text.

ActiveCN113826102BText databaseEngineering
This disclosure relates to a communication server apparatus, a communication device, and a method of operating the same. A communication server apparatus (100) is configured to receive (202) text data comprising at least one text data element associated with an abbreviated text unit. The text data element is compared (204) with a plurality of candidate text data elements from a given text database, each candidate text data element being associated with a corresponding candidate text unit in the database. A similarity metric between the at least one text data element and these candidate text data elements is determined (206), and the candidate text data elements are processed (208) to select candidate text data elements that have an ordered relationship with the abbreviated text unit. These similarity metric values ​​and the selection of these candidate text data elements are used (210) to designate the associated candidate text unit as the de-abbreviated text unit of the abbreviated text unit.
