Entity relationship recognition method and apparatus

The present invention relates to an entity relationship recognition method and apparatus. The method comprises obtaining a statement sequence from a target text in a corpus, and performing named entity recognition and dependency grammar marker on the statement sequence to obtain a marked text sentence; matching and retrieving the marked text sentence on basis of an entity relationship seed to obtain a training example; replacing the entity relationship seed word in the training example with predetermined identification, processing the training example after replacement combined with the named entity recognition and the dependency grammar marker, and generating a candidate rule; fuzzifying the candidate rule to obtain fuzzy rules; determining whether the fuzzy rules comprise a new rule; and retrieving the corpus according to the fuzzy rules to obtain a seed set when the fuzzy rules comprise the new rule, and using the obtained seed set as an entity relationship recognition result. Manual participation can be effectively reduced, dependence on the calibrated corpus is reduced, a new entity relationship can be found timely, and the entity relationship recognition method and apparatus are self-adaptive to entity relationship mining in different fields.

Monitoring data intelligent sampling method based on relevancy analysis

The invention discloses a monitoring data intelligent sampling method based on relevancy analysis, which includes the four key steps: time series data encoding, relevance relationship mining, state transition matrix calculation, and state prediction. According to the method, a monitoring cycle can be dynamically adjusted according to the prediction on future resource usage of a main unit, thereby reducing sampling frequency while resource usage varies stably, and increasing the sampling frequency while the resource usage varies sharply to save computing and storage resources. Compared with the prior art, the method has the advantages that the monitoring cycle can be enlarged and sampling frequency can be decreased while a machine runs stably; when the machine running fluctuates, it is required to decrease the monitoring cycle and increase sampling rate; more meaningful monitoring data are acquired, the quantity of gibberish to be collected is decreased effectively, spending major computing resources to on gibberish acquisition, computing and other processing is avoided, efficiency is improved, and high accuracy is maintained while gibberish collection is reduced.

Proactive caching method based on content popularity and movement rules of users

The invention discloses a proactive caching method based on content popularity and movement rules of users. By introducing social relationship mining, users in a small cellular network are subjected to community division, and according to a Zipf law, content popularity distribution of each community is analyzed; by a frequent pattern mining algorithm, the movement rules of the users are mined, andaccording to a rule confidence degree, probability distribution that the user accesses each base station in a next time period is acquired; and according to content request distribution of the usersand probability distribution of accessing to each base station, under limited cache capacity of each base station, a cache hit ratio is maximized by optimizing a caching strategy. By adopting the proactive caching method disclosed by the invention, a return load can be reduced, and a user delay is reduced; and meanwhile, the method has the decomposition characteristic and is low in algorithm complexity.
