Multi-granularity semantic chunk based entity attribute and attribute value extracting method

The invention relates to a multi-granularity semantic chunk based entity attribute and attribute value extracting method, and belongs to the technical field of Web mining and information extraction. The method comprises the following steps that a corpus set is constructed and free text extraction is performed; a corpus is subjected to word segmentation, part-of-speech tagging and phrase recognition; the corpus is subjected to semantic role labeling; the corpus is subjected to dependency grammar analysis; the corpus is subjected to semantic dependency analysis; candidate entities, attributes and attribute value triads based on three granularities of words, phrases and semantic roles are extracted; the candidate entities, attributes and attribute value triads are corrected and subjected to error classification by means of a trained classifier. Compared with the prior art, the entities, attributes and attribute value triads based on three granularities of words, phrases and semantic roles are automatically extracted from a free text, the entity attribute and attribute value extraction accuracy and efficiency are improved, and the wide application prospect is achieved in the fields of theme detection, information retrieval, automatic abstracting, question and answer systems and the like.

Energy-efficient resource allocation method for use in heterogeneous wireless network

InactiveCN104869646AImprove energy efficiencyImprove Uplink Energy EfficiencyHigh level techniquesWireless communicationEnergy efficient resource allocationRadio access technology
The invention provides an energy-efficient resource allocation method for use in a heterogeneous wireless network. The method comprises the following steps: initializing power allocation of mobile terminals; determining the energy-efficient bandwidth resource allocation of a radio access technology; determining energy-efficient power resource allocation of each mobile terminal; adjusting the transmitting power of the mobile terminals, and calculating an energy efficiency sum; and repeating the steps above till the value of the energy efficiency sum of the heterogeneous wireless network is maximum. According to the energy-efficient resource allocation method, the energy-efficient bandwidth resource allocation is calculated firstly, and the energy-efficient power resource allocation is determined according to the bandwidth resource allocation, so that the value of the energy efficiency sum of the heterogeneous wireless network is increased after each resource allocation. Then, the steps above are repeated till the value of the energy efficiency sum is converged, and energy-efficient co-allocation of bandwidth resources and power resources is achieved, so that the uplink energy efficiency of the whole heterogeneous wireless network is increased.

Three-network amalgamation method and system

The invention provides a three-network amalgamation method and a system. In the method, data provided by an internet application server for a computer are transmitted through a telecommunication network and a broadcast television network, and the method comprises the following steps: 1, a computer terminal logs in a data pushing system through a telecommunication network bi-directional passageway so as to obtain a broadcast television network resource distributed for the computer terminal; 2, the application of the computer terminal accesses internet application websites through a bi-directional passageway of the telecommunication network so as to send a service request to the internet application server; and 3, the internet application server returns data, and the computer terminal acquires the returned data through the distributed broadcast television network. The data pushing system is arranged in the broadcast television network and used for connecting the computer terminal and an IPQAM (Internet Protocol Quadrature Amplitude Modulation) device so as to manage and distribute the IPQAM device resource and push the data to the computer terminal through downlink data of the broadcast television network. The scheme disclosed by the invention minimizes the use of telecommunication network uplink resources and maximizes the use of broadcast television network downlink resources.
