Embodiment
Technical thought of the present invention is:
This method is mainly from the history development Experience of the angle analysis software maintenance staff of semanteme, and it mainly utilizes the software maintenance staff that association's related subject model (CollaborativeTopicModel is called for short CTM) recommends out one group of working experience similar and the associated documents that they once revised.Recommend maintainer out all familiar to amendment bug, and have and ask relevant working experience to this amendment bug, therefore, these maintainers can exchange together and jointly realize this software maintenance task.
Joint relationship and topic model combine by association's related subject model (CollaborativeTopicModel is called for short CTM).This model not only can find out the personalized task of related development personnel, a new task can also be recommended the developer of similar development Experience.We mainly find the developer with similar development Experience by association's related subject, then analyze the associated documents that these developers once revised jointly, according to the cyberrelationship between these file set up associated developer.When developer is when revising certain source code file and meeting difficulty, he can find out the software developer of other these files more familiar by this network graph of a relation of throwing the net and exchange with him, when the bug amendment of some complexity, even can find out multiple developer and form group and realize software maintenance task together.
Illustrate the present invention below.
As shown in Figure 1, practical operation step of the present invention is as follows:
Step 1). carry out entry division, root process to all Commit information in the software bug information of System Reports personnel, sound code file storehouse and history amendment storehouse, the inquiry of gerund synonym, near synonym is expanded vocabulary and is carried out pre-service.Fig. 3 mainly gives the information schematic diagram of Commitr10218 in Hadoop project, and we are mainly to Commit information pre-processing, and to the pre-service of the associated documents in Commit mainly in file part process.Such as: to information " ProvidebettererrormessageswhenRPCauthenticationfails. " the pretreated result of Commitr10218 in Hadoop project be: " hadoopproyidbetterbreakerrormistakeerrorfaultmessagrpcau thentfailneglectHADOOPProvidesupplyproviderenderfurnishm essagesRPChallmarkassay-markfails ".
Step 2). with cosine function, Similarity Measure is carried out to all pretreated Commit storehouses and pretreated bug, according to Commit information and the relevant Commit of word multiplicity identification in bug information.Wherein the computing method of cosine function are:
relCommit bug = | commit &cap; bug | | commit &cup; bug | - - - ( 1 )
In formula (1), relCommit bugrepresent all Commit information relevant to bug.| Commit ∩ bug| represents the word quantity jointly had in Commit and bug information, | Commit ∪ bug| to represent in Commit and bug information word quantity altogether.All Commit that this step obtains are relevant to software bug information, therefore we can extract software developer in these Commit and, as the candidate of amendment software bug information, extract the relevant sound code file of the sound code file in these Commit as amendment software bug information.Therefore, the relevant Commit quantity that this step obtains is comparatively large, and such as, the Commit that bug_1123 is relevant after calculating in Hadoop project has 268 relevant Commit.
Step 3). after obtaining all Commit relevant to bug information, developer is extracted in relevant Commit information, and extract the relevant sound code file that each developer revised and form a < developer, relevant sound code file > corresponding lists.The relevant sound code file of part that developer JingZhao with HaohuiMai be such as correlated with for bug_1123 in system revised provides respectively in figures 4 and 5, this part correlated source code file is not only all relevant to software bug information, and be all the file that this developer once revised, so the relevant sound code file of each developer is different.Such as, the file in Fig. 4 and Fig. 5 is the file that JingZhao and HaohuiMai once revised respectively, and their file is all different, has respective amendment or operating habit.
Step 4). by step 3) result < developer, relevant sound code file > carries out association's correlation computations as the input data of association's related subject model (CTM illustraton of model is as Fig. 2).Obtain the concrete related development personnel of the bug information that realizes and the personalized sound code file of these developers.The personalized sound code file of part of developer JingZhao and HaohuiMai be such as correlated with for bug_1123 in system provides respectively in figure 6 and figure 7, these personalization files tentatively can reflect the history development Experience of developer, so according to the personalized sound code file of every developer, system tentatively can find out the relevant software developer of development Experience, such as the first two personalization files of these two developers of JingZhao with HaohuiMai is the same, and therefore their development Experience tentatively judges to be correlated with.In order to analyze the correlativity between developer further, lower plane system will analyze the history development Experience of developer further in conjunction with Commit storehouse and sound code file storehouse.
Step 5). in conjunction with pretreated Commit storehouse and pretreated sound code file storehouse, analyze the history amendment situation of every developer to these source code file, Main Analysis developer revises the number of times of this sound code file and the time of amendment recently.Such as: the old version amendment situation of system to the personalized sound code file hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSNamesystem.java of JingZhao provides in fig. 8, as can see from Figure 8, except JingZhao crosses FSNamesystem.java file modification, other a lot of members are also had to revise this file, wherein revise number of times more, time nearer personnel mainly contain AndrewWang, HaohuiMai and None.Therefore, we can build cyberrelationship figure to all related development personnel according to these old version information.
Step 6). according to the history amendment situation of source code file, set up the graph of a relation between developer.The cyberrelationship figure of such as, other developers centered by the developer JingZhao be correlated with for bug_1123 in system provides in fig .9, wherein, data on line represent the common personalization files quantity of developer between the two, quantity of documents is more, illustrates that their development Experience is more similar.When JingZhao is when revising bug_1123 and meeting difficulty, he can find out other proper developers according to this figure and exchange, or bug_1123 is reassigned to other related development personnel, even can forms maintenance group maintenance software system together.
