2 results about "Time expression" patented technology

The application relates to the technical field of knowledge graph and information processing, and discloses a scientific and technological innovation capability intelligent analysis method and system based on a time sequence event graph, which comprises the following steps: performing standardized processing, entity identification and event assembly on multi-source scientific and technological innovation data, and constructing a time sequence event graph containing time boundary information; establishing a subject partial order index based on an event time interval to depict the sequence of events; for newly arrived events, event merging and version management are realized through candidate alignment scoring, and event versions participating in calculation are determined through activity weight; when an activity version changes, affected subgraphs are identified and local representation is updated, and a scientific and technological innovation capability analysis result is generated in combination with an event path. The method can effectively solve the problems of inconsistency of multi-source data, uncertainty of time expression and dynamic updating of data, and improves the accuracy and stability of the analysis result.

This invention discloses an internationalized time-aware recall method based on text time semantic parsing, comprising the following steps: S1. Receiving user input; S2. Complexity classification; S3. Adaptive time semantic extraction: an adaptive time semantic extraction strategy extracts time expressions from natural language text; S4. Time normalization: converting the time expressions into standardized time interval representations; S5. Time zone processing: converting the time interval representation into a timestamp of a standard time zone according to the user's time zone parameters; S6. Time-constrained memory retrieval: performing time-constrained memory retrieval in a vector database based on the time interval representation; S7. Outputting memory results: returning the memory results to the user. This invention supports multiple expression forms such as absolute time, relative time, fuzzy time, and time range, supports multilingual extensions including Chinese, English, and Japanese, supports global time zone conversion, and achieves end-to-end time-aware memory recall, significantly improving user query efficiency and user experience.
