When collecting raw information, except collecting above-mentioned content of text, can also collect Tag (classification or keyword), Rank information such as (positive rating or clicking rates).
Step 20, from step 10, extract geographical location information and hierarchical information in the collected raw information, form data entries.Information extraction is meant a category information that extracts appointment from one section text, and with its structuring, inserts the process of using for user inquiring in the database at last.Wherein, geographical location information is meant as information relevant with the geographic position such as place name, sight spot name, city name, building names, and hierarchical information is meant the information after the geographical information categorization division, for example, administrative division (administrative area, city, economize country, continent etc.), (as: Four Girls scenic spot, scenic spot, the Huashan) divided at the scenic spot, and route (street, highway, national highway, expressway, railway line, course line etc.).
In step 10, collected raw information may be the information of html format, also might be the information of XML form.For the information of html format, adopt regular expression (Regexp) to extract described geographical location information and hierarchical information, utilizing the regular expression information extraction is ripe prior art, does not do detailed explanation in the present embodiment.For the information of XML form, adopt the XML switch technology, as XSLT, extract geographical location information and hierarchical information in the raw information.Raw information is stored in the SQL database through after extracting, putting in order.
In raw information cited in the step 10 about the Summer Palace, through behind the information extraction of this step, the geographical location information that can obtain being correlated with, as " Summer Palace, the Longevity Hill, the Foxiang Pavilion, Kunming Lake, Beijing " etc., resulting hierarchical information is " China, Beijing, Haidian District " etc.
When making information extraction, not only in raw information, find corresponding geographical position information and hierarchical information, also to finish coordinate transformation and zone association.
Coordinate transformation is meant to be handled geographical location information that extracts and hierarchical information, makes it corresponding with absolute coordinates or coordinates regional respectively, thus the mapping table of coordinate on the place name of foundation and the map.Owing in different geography information, may have different geographic coordinates,, the unification of mile unit need be converted to a kilometer unit as kilometer and mile; Also may need relative coordinate is converted to absolute coordinates, as scenic spot intrinsic coordinates scope is projected on the absolute longitude and latitude.Therefore all need coordinate is transformed.
Zone association is meant extracts geographical location information and hierarchical information is handled, and information not only is associated with the geographic position at this information place, also will make this information related with the relevant information work in geographic position.For example, aforesaid raw information about the Summer Palace is with after " Summer Palace " this keyword is related, also related go up " Beijing ".
After finishing the operation of above-mentioned coordinate transformation and zone association, data combinations such as raw information and the geographical location information that extracts and hierarchical information are in the same place, can form data entries.The general description of data entries is as follows:
INFO-ITEM∷=(TEXT,MULTIMEDIA,TAG,RANK,COORDs,REGs,LAYER,ROUTEs)

Table 1
In above-mentioned data entries, the longitude and latitude of a certain place name can obtain by searching place name-longitude and latitude mapping table.In general data entries, also should comprise relevant informations such as the picture at the sight spot of describing, residing route, because the photo resolution after dwindling is too low, can't in application documents, clearly represent, be not listed in the above-mentioned table 1, but those skilled in the art should know that data entries also can comprise information such as picture.
Step 30, that binding is done in the data entries and the position of Geographic Information System (GIS) that step 20 is obtained is related.Geographic Information System (GIS) is a system that stores information such as map, coordinate, route, place name, topological structure, hierarchical structure, related being meant of binding done in the position of data entries and GIS will set up corresponding relation to information of being correlated with the geographic position that obtains in the step 20 and coordinate (longitude and latitude) or the coordinates regional on the map among the GIS, this corresponding relation may be the relation of one-to-many, multi-to-multi.
Geographic Information System is ripe prior art, in the present embodiment, gets a Geographic Information System about China, according to the longitude and latitude in the data entries, the corresponding longitude and latitude in data entries and this Geographic Information System is bound.For example, the longitude and latitude in the aforesaid Summer Palace is 116.2688E, and 39.9977N finds the point corresponding with this longitude and latitude so in Geographic Information System, will do related with this point about the data entries in the Summer Palace.Also can make similar operation with it for other forms of data entries.
Step 40, related with it data entries is carried out analysis-by-synthesis, polymerization according to the relation between the GIS coordinate position.
Because each data entries all has one or several relevant geographical absolute coordinates (longitude and latitude) as " characteristic parameter ", therefore data entries is performed an analysis, during polymerization, with the foundation of geographical absolute coordinate as polymerization, the information fusion of close having " characteristic parameter ", and the mode mark with " piling " comes out on map.
The polymerization of data entries can be divided into three kinds, is respectively label aggregation, coordinate polymerization and region clustering.It is object that label aggregation wherein is meant with the keyword, utilizes mathematical statistics to carry out polymerization, realizes the classification reorganization of information, and this polymerization is corresponding to the TAG in the data entries; It is object that coordinate polymerization wherein is meant with the coordinate, the polymerization that utilizes geometry to carry out, and this polymerization is corresponding to the COORD in the data entries; It is object that region clustering wherein is meant with the zone, and the polymerization that utilizes concept hierarchy to carry out is corresponding to the REG in the data entries.
The implementation of two kinds of coordinate polymerizations has for example just been described in Fig. 2 and Fig. 3.Fig. 2 gets together the information of distance " close " exactly for closing on the coordinate polymerization.2 of A among the figure, B are comparatively approaching, therefore can condense together data entries 1 relevant with an A and the data entries 2 of being correlated with a B.Fig. 3 is coordinate polymerization along the line, exactly the peripheral information of circuit between some is condensed together.A among Fig. 3 near their lines, has a some C to being a circuit between B, and system can also mark near the place C the AB line, offers more reference of user.If A represents Beijing, B represents Shenyang, and to Qinhuangdao C is arranged between the B, C marks on map with Qinhuangdao at A, can provide a nearer sight spot for referencial use for the trip of the visitor from Beijing to Shenyang on the way more.Except above-mentioned coordinate polymerization, the polymerization of route can also be arranged.In Fig. 4, have two lines be respectively A to B and C to D, an intersection point is arranged between two circuits.Can generate new circuit by polymerization, as can be to C by A, by B to D etc.
When specific implementation, to Tag and COORD (REG, the LAYER of resulting data entries in the step 30, ROUTE) add up, the coordinate points (city, sight spot etc.) that polymerization is contiguous is found out the focus of attention, sets up the focus of each layer (city-level, provincial) then and sums up.In addition, system can find the point of crossing of tourism route, merges similar tourism route or generates new route.Use inner inquiry that the focus of attention is inquired about, the result of inquiry is deposited in the SQL database as summary information.
For the data entries described in the table 1 about the Summer Palace, can be higher because of the RANK value of this data entries, this data entries is aggregated in the keyword place clauses and subclauses of " Beijing one-day tour ".
Step 50, user inquire about in travel information aggregated service system, and Query Result shows in the mode of two dimension.
When the user inquires about, on electronic chart, can click, delineate or the frame favored area with mouse in different positions, or the mode of input keyword and selection classification, the inquiry specifying information.The inquiry of two-dimensional approach has following characteristics:
A, can carry out self defined area retrieval, when the user does not understand area-name or the regional place name that may comprise, can directly on electronic chart, delineate the target search zone, help the user to avoid importing the difficulty of strange place name keyword, and represent a certain zone intuitively than text description is easier.For example, in the time of seeking near the hotel certain railway station, the user can this railway station be that the center describes a circle, and selects classification (hotel's lodging), can obtain the information in all hotels in this zone.
B, level retrieval, the user can be as required, the information of retrieval different levels.For example, that the user can retrieve is provincial administrative region, the city-level administrative region, the map of level administrative region, district, and the information that the different levels map can provide exists difference.
The retrieval of c, detailed degree gradual change, system can provide a general picture in the high zone of importance (RANK) on map, and then clear gradually, when the user is unsatisfied with PRELIMINARY RESULTS, can initiate soon to retrieve again, reaches quick, practical effect.
D, peripheral relevant information polymerization when Query Result merges mutually with prior two-dimensional signal polymerization, can obtain the polymerization result of peripheral relevant information.For example when certain museum of inquiry, can provide the positional information in these ten big focus museums, city simultaneously.
In the present embodiment, travel information aggregated service system provides the multiple retrieval mode that comprises combined retrieval.On search interface, the user can select classification by the input keyword, and convergent-divergent drags map, or puts favored area and search, and also can directly specify longitude and latitude to come localizing objects.System uses Apache and PHP to build a Web server (Web Server), provides basic Web function such as authentification of user, files on each of customers, click statistics.PHP can represent multiple inquiry form, user's information inquiry parameter (Query) is converted into the SQL query language goes out Query Result from database retrieval.
After obtaining Query Result, show Query Result in the mode of two dimension.Two-dimensional signal shows to be exactly each position that message header is distributed in map.This displaying and traditional electronic chart are similar, but the content that the conditional electronic map is showed is static place name, road name etc., can only show with a kind of result for different people.But that the travel information aggregated service system in the present embodiment is showed with two-dimensional approach is the result of user inquiring, if user's query contents difference, even the map of areal, the content that it is showed also is dynamic change.
Realize the two dimension displaying of Query Result, service system is used JavaScript, and AJAX (AsynchronousJavaScfipt and XML) expands demonstrating one's ability of browser.JavaScript is responsible for the control of user interactions, user's querying condition is sent to server, obtain result for retrieval from server by HTTP again, pass through the displaying contents of dynamic HTML (DHTML) operating browser then, with the form demonstration result for retrieval of two-dimensional visualization.Visualization view is demarcated the coordinate of result for retrieval clauses and subclauses with base map as a setting with symbol on map, and show title, also with arrow line segment demonstration route.In addition, the result also represents to the user in traditional tabulation mode simultaneously.
Suppose some users with " Beijing one-day tour " as the keyword that will search for, the relevant information that then comprises the Summer Palace and other famous sight spots, Beijing among the result who is searched, and can on electronic chart, identify the wiring diagram at the above-mentioned sight spot of how playing, and information such as address, public bus network.
