Core Competence:
Top level of problem analyzing,abstractionandsolving.
Top level ondataprocessingandcorrespondingalgorithm.
Has extraordinary insightonsearchengines anddatamining.
Has the abilityof graspingthe essence of the probleminfew minutes usually.
Groundbreakingthings done:
1. WIFI positioningbasedondatamining thought.Accuracy can reachto the limitof
statistical theory.
2. Firstlyproposedthe thoughtthatJudge whetherthe contentof a webpage isduplicated
accordingto its URL. Base onthismethod,we can distinguishandgetridof 60%
webpage URL whose contentare duplicatedwithoutdownloadingthe webpage.
3. Have a patentinChinaon webpage analysis.Analyze the webpage withthe thoughtof
webpage general templateandgreatlyincrease the accuracyof webpage analysis.
4. Recognition onmirrordirectory
5. Image recognitionfield:Identify the rasterimage anditsvectorization.

Position:Mapsearch,Technical Lead
1. POIProcessing
- Polymerization large POI name,suchas gates,contour,parkingandother
information.ReachabetterresultthanBaiduwhenproductonline.

2. - Multi-source datafusion:Fuse datafrommultiplePOIdataand POIdata
downloadedfromwebsiteaccordingtothe feature of POI,takingadvantage of the
rule of POI distribution.Greatlyincreasedthe accuracyof data fusion.
- On wrong POI discovery aspect, bring up the thought of excavating from coordinates,
address,andlarge poi relations;Accordingtothe feature of POI,fuse same POIin
differentnames.
2. POI Search
- Firstlypropose the thoughtof poi address chainsearchand itsreal realizationreach
a bettereffectthanBaidu.
- From the perspectiveof geographicinformation toanalyze the searchterm,thento
determine the location orarea
3. WIFI Positioning
Currentlythe commonWIFIpositioningmethodis three pointspositioning.
I broughtup a thought. Get the minimal confidence intervalaccordingtoWIFI
information.Thismathematically achieve tothe optimal results.This theorycanbe
appliedtoany annotated data mining,andgetto the optimal resultsintheory.
Solve the problemof positionjumpaccordingtothe statistical probability.
Solve the problemof the determinationof minimalconfidenceinterval.

1. Data Mining:
- Words cut aspect,include thesaurus generatingandword cut algorithm.
2. Online Map:
- optimizingthe structure of the original hashindex andreduce original size to600
times.Slightlyfasterthanthe original hash.
- Successfullyanalyze the Baidumapcoordinate.Baiducoordinate isoriginallyknown
as no one isable to breakdue to its difficulty.
3. Image processing:
- Vectorgeneratingto the rasterimage,includingimage conversion,recognition,
pumpingpoint, Polygonsegmentationandfill shapes.
- Recognitiontotelephone numberinimage formattoKoubei website.Convert
digital informationtotextinformationinside animage.The accuracyreach to 100%.
