Specific implementation mode
The present invention is described in further detail with specific implementation mode with reference to the accompanying drawings of the specification.
Fig. 1 shows a kind of flow chart of the analytic method of buying acceptance of the bid data, the party in the specific embodiment of the invention
Method may comprise steps of：
Step S100：Isolate the list data in Html buying acceptance of the bid bulletin texts to be resolved and non-standard table number
According to；
Html buyings acceptance of the bid bulletin text to be resolved is pre-processed first, delete in buying acceptance of the bid bulletin text with
The unrelated data for content of getting the bid.It is purchased in acceptance of the bid bulletin text in actual Html, has many and actual acceptance of the bid content
Unrelated data, such as show in relation to the data of (font, size, the color of text) or other be not related in essence with text
The content of data is marked, therefore the deletion of these data can be carried out in advance, to improve the efficiency of follow-up data processing.
In practical applications, Html buying acceptance of the bid bulletin texts can be found out according to the display class label in Html texts
In only shown with data in relation to, with the unrelated data of acceptance of the bid content, delete Html buying acceptances of the bid announce in text with acceptance of the bid
The unrelated data of content.Wherein, the display class label includes but not limited to for defining the font of word, size and color
<font>Label, for the section in definition document<span>Label and without meaning space etc..
In present embodiment, the list data includes criteria table data and non-standard list data；The standard scale
Lattice data refer to that the acceptance of the bid bulletins attribute specified in list data is located at same a line, the data of different lines in table, in specified
Mark bulletins attribute includes but not limited to supplier and the acceptance of the bid amount of money.The list data as shown in Fig. 4 is criteria table number
According to offerer's title, that is, supplier and bid amount are to get the bid the amount of money positioned at same a line and difference positioned at table in the table
Row.Data except non-standard list data, that is, criteria table data.
In present embodiment, the acceptance of the bid bulletins attribute include project name, supplier, acceptance of the bid the amount of money, purchaser and
One acceptance of the bid candidate's mark etc., it should be noted that in different acceptance of the bid bulletins, the title for bulletins attribute of getting the bid might have
Institute is different, and acceptance of the bid bulletins attribute can be named according to actual conditions, and if supplier may also be known as offerer, the acceptance of the bid amount of money may
Referred to as bid amount.
In present embodiment, the criteria table data and standard in Html buying acceptance of the bid bulletin texts to be resolved are isolated
The concrete mode of list data is：
1) all tables in Html buying acceptance of the bid bulletin texts are isolated according to the form tag table of Html texts；
All tables include sub-table nested in table；
2) judge whether the acceptance of the bid bulletins attribute specified described in table meets same a line and different lines positioned at table, if
It is, it is determined that table is criteria table, and the data in criteria table are criteria table data, if not, it is determined that table is non-
Criteria table, the data in non-standard table are non-standard list data.
In practical applications, by nesting<table>(<table>Contain<table>) separation be independent N number of son<table
>.Per height<table>Label be all with "<Table " beginning with "</table>" terminate, by keyword "<table>" and
“</table>" position and count, nested son is found out successively<table>Label is detached one by one, obtains each height<
table>The complete character string (list data) of label parses recursive algorithm as suction parameter recursive call data.
All (embedded with not comprising nested)<table>After tag processes, the public text of acceptance of the bid is completed
The separation of Plays list data and non-standard list data, criteria table data as shown in Figure 4 are non-as shown in Figure 5
Criteria table data.In practical applications, the acceptance of the bid bulletins attribute specified with specific reference to which determines criteria table and nonstandard
Whether quasi- table can be selected as needed, in present embodiment, by judging supplier and the acceptance of the bid amount of money in same a line
To determine whether being criteria table, if be in two necessary conditions of same a line：
1) in different lines：Between the position A of supplier and the position B of bid amount comprising cell label "</td>”；
2) in same a line：Between the position A of supplier and the position B of bid amount do not include row label "</tr>”.
Table as shown in Figure 4, wherein offerer's title (supplier) and bid amount meet above-mentioned two necessity item
Part then judges the list data in Fig. 4 for criteria table data.
Step S200：According to buying get the bid bulletin text acceptance of the bid bulletins attribute respectively to criteria table data and non-standard
List data is parsed, and acceptance of the bid record is obtained；
After isolating criteria table data and the non-standard list data in text, respectively to criteria table data and nonstandard
Quasi- list data is parsed.Since there are nest relations in list data, to criteria table data and non-standard list data
It when being parsed, is parsed from the data of innermost layer nested tables according to the nesting order of table, completes one layer of list data
Parsing after, delete the list data of respective layer, parse the outer form data of this layer again later.Using parsing from inside to outside
Mode can ensure not interfered by nested tables label when outer form tag processes, and acceptance of the bid record is obtained with more accurate.
In present embodiment, the concrete mode parsed to criteria table data is as shown in Fig. 2, included the following steps：
1. obtaining the row number for bulletins attribute of respectively getting the bid in criteria table data；With the entitled keyword for bulletins attribute of getting the bid
The accurate profit number residing for each attribute, list data as shown in Figure 4 are oriented in retrieval in list data, and supplier's row number is
2, the row number of the first candidate mark is 5；
2. every a line in circular treatment table obtains each acceptance of the bid per a line according to the row number of each acceptance of the bid bulletins attribute
The value of bulletins attribute obtains the acceptance of the bid record of every a line.Every a line in criteria table data corresponds to an acceptance of the bid record.
The second row in criteria table data as shown in Figure 4, the acceptance of the bid parsed are recorded as：Supplier：Guangzhou
Xingu Electronic Science and Technology Co., Ltd. of city, the acceptance of the bid amount of money are 246000, which is the first candidate.
In present embodiment, non-standard list data is parsed using text string analytic method, the flow of parsing is such as
Shown in Fig. 3, specifically include：
For a non-standard list data, with the associated prefixes or suffix of get the bid bulletins attribute or bulletins attribute of getting the bid
It is retrieved in non-standard list data for keyword, obtains the attribute value of each acceptance of the bid bulletins attribute, announced according to each acceptance of the bid
Attribute and its attribute are worth to an acceptance of the bid record.
In practical applications, it is necessary first to orient the title of supplier, can with " supplier " or " offerer ",
" quotation company " etc. is retrieved for keyword in subpacket data, if can not find, can be according to the association of supplier before
Sew or suffix carries out matched and searched, for example, had as previous in the title of supplier "：" etc. special prefix or one in title
As have suffix such as " companies ", can according to these prefix or suffixes carry out supplier retrieval position.Complete determining for supplier
Behind position, the acceptance of the bid amount of money and other acceptance of the bid bulletins attributes are further parsed, it is similar to supplier's positioning, it can be with bulletin of getting the bid
Title that attribute is (such as " the acceptance of the bid amount of money ") is that keyword is directly retrieved, if retrieval is less than can be according to relevant association
Prefix or suffix is searched (such as the association suffix " volume " of " the acceptance of the bid amount of money ", " member ", " valence ").
In the parsing for completing criteria table data and non-standard list data, after obtaining acceptance of the bid record, in order to ensure to get the bid
The integrality of record can also obtain the entry name of acceptance of the bid record by conventional keyword match method in practical applications
Other relevant informations such as title, expert.
Step S300：In the acceptance of the bid record storage to database that parsing is obtained.
By the parsing in step S200, after the acquisition for completing acceptance of the bid record, acceptance of the bid data are stored into database.

Validity is judged, and carries out the duplicate removal processing of acceptance of the bid record.
In present embodiment, it is underway label record Effective judgement when, can according to acceptance of the bid bulletins attribute attribute
Value judges whether acceptance of the bid record is effective, if so, retaining acceptance of the bid record, if it is not, then deleting acceptance of the bid record.For example, passing through
Judge that supplier verifies whether effectively or whether the acceptance of the bid amount of money is 0 or whether is the modes such as the first candidate supplier to judge to remember
Whether record is effective, generally, if supplier and the acceptance of the bid amount of money do not have apparent problem, it may be considered that an acceptance of the bid record is effective
Acceptance of the bid record.
In present embodiment, it is underway label record duplicate removal processing when, according to acceptance of the bid record belonging to table mark and
The attribute value of its bulletins attribute of getting the bid judges the repetition record in acceptance of the bid record, and carries out duplicate removal processing；Judgment mode is：If two
It is a acceptance of the bid record belonging to table mark it is identical and its get the bid bulletins attribute attribute value it is identical, then judge two acceptance of the bid record weight
It is multiple.Wherein, the mark of the table is for one table of unique identification, in the non-standard list data as shown in Fig. 5, packet
Included three non-standard list datas, table belonging to three non-standard list datas mark is non-be not " packet one ", " wrapping two " and
" packet three ", in general, in the acceptance of the bid bulletin text of Html formats, each table is identified with it, if not provided, this implementation
Can give tacit consent in mode is that each table distributes a unique identification number.
After the validity and duplicate removal processing for completing acceptance of the bid record, the relevant information of effective acceptance of the bid record is saved in number
According in library.
