To meet the needs of power producers in production, operation and bidding for access to the Internet under new situation, we e develop the operation decision support system for power generation enterprises. The system includes cost characteristic analysis module, bidding analysis module, quotation strategy module, real-time quotation system module, real-time cost tracking module and transaction evaluation system module. In the key electricity price forecasting module, the cost analysis algorithm based on genetic optimization algorithm and bidding strategy based on game theory are developed. The testing results show that the operation decision support system of the power generation enterprises runs well and the forecast price is more accurate, which provides the technical basis for the power generation company to compete on the Internet and it provides strong support for future survival and development.

With the rapid development of web technology and the popularity of Internet technology in the public, people continue to use computers to store a variety of information, the amount of data stored is growing, and the kind are becoming more and more abundant. At the same time, the diversity of data storage has increased the diversity of unstructured data. The basic characteristics of unstructured data are diverse data formats, large data storage, and fast growth. This paper first summarizes the content and characteristics of unstructured data, then analyzes the key to unstructured data retrieval, and designs and develops a Python-based unstructured data retrieval system using Python language.

To quickly and accurately retrieve the required music songs from the mass music database, this paper introduces the framework of content-based audio retrieval system and its related characteristics and difficulties. Then it describes the process of human voice humming feature processing on the voice platform within the framework of the system. On the simulation music platform, the retrieval algorithm based on the combination of notes and fundamental frequency is studied and analyzed for songs with background music, combined with the relevant characteristics of audio signals. The accuracy of humming retrieval can be improved by using more accurate iterative alignment algorithm of stress shift. The experiments show that the average retrieval time of humming retrieval system is significantly reduced by using the retrieval strategy.

This paper combines the conceptual construction and classification methods of geo-ontology, explores the method of formal description language to express geo-domain ontology concepts, and defines the concept of geo-ontology in the process of geo-spatial information semantic expression. Controposing to the problem of inadequate description of spatial information services by traditional description methods, Construction of spatial information application ontology with Protege tool and description service information with OWL-S description language are adopted, to realize the semantic integration between geo-information system. It constructs spatial information application ontology and describes service information with OWL-S description language. The elements of service quality are expanded to improve the comprehensiveness of service description. To verify the feasibility of the combination of theory and practical application of geo-ontology, a mobile GIS is developed from the bottom under the support of current mobile development technology, and an example of spatial semantic retrieval is tested. The superiority of geo-ontology in semantic retrieval is verified, which has important theoretical and practical significance.

After visiting the historical urban area of Shantou and exploring customs of local residents for a long time, We absorbed people's memory of Shantou. Combining document's research, we have got the developmental traces of this land. Then we intend to do some renovation of architecture and landscape. By reactivating such trace of memory, giving the residential sites new functions, and many others designs to express our tribute to history. The city has somewhere to stay, and the author has something to pursue. What the author pursuing is that returned history to our city through a series of small changes, to reserve the memories of local residents' life.
