7. What is Semantic Search? Semantic is meaning In recruiting, semantic search would ideally identify the right candidates Resume Job Description Resume Resume Resume 3
16. “Boolean” Approach Example Pick keywords from a job description and create Boolean strings Software Engineer. You’ll help build next-generation security products, working as part of an energetic team and hacking in a Linux/Mac/open source environment The ideal candidate has: * 3+ years software development experience (Demonstrable fluency in C/C++) * Demonstrable fluency in Ruby, or another interpreted, open source language (Python, Perl, PHP, etc.) * A Bachelor’s degree in Computer Science, Mathematics or equivalent work experience * TCP/IP experience, up and down the stack * RDBMS familiarity, including entity design and SQL query troubleshooting 9
17. “Boolean” Approach "software engineer” Linux "open source" C++ Ruby TCP/IP SQL “7,000+" results (an estimate);not right – mostly job posts "software engineer” Linux "open source" C++ Ruby TCP/IP SQL -jobs -job about 700+results (not bad!; many are resumes, some are not) intitle:resume | inurl:resume "software engineer” Linux "open source" C++ Ruby TCP/IP SQL about 75 results(good but we want more) intitle:resume | inurl:resume "software engineer” | developer Linux | UNIX "open source" C++ Ruby | Perl | python | PHP TCP/IP SQL about 700 results; pretty good; can play with it and look at the results 10
18. “Semantic” Approach May… Recognize the title, keywords, must-haves, locations Suggest alternative terminology, abbreviations, target companies, colleges Search for resumes that have target titles, must-have keywords in the recent experience 11
19. Still, Any Tool Requires Human Input Real life challenge: “Тhey would like the functional candidates to come from similar consulting firms or recently in a consulting firm. They want to see some stability. For the technical roles – they need consulting, not out of industry. Except for the hard-to-find roles like Business objects.” 12

25. Semantic Features – Web Search Engines Tilde ~ allows to search for synonyms 18
26. Semantic Features – Social Media Structured profiles allow meaningful search (but no synonyms recognition) 19
35. Parsing Tools By parsing search results we can narrow them down to those that are likely to be on target Example: Find resumes using the keyword Microsoft, parse, and pick those where Microsoft means employer 23

37. For a limited set of structured documents (such as a resume database), than for the web24
46. Semantic Search For Recruiters:Functionality (cont.) Allow users to give weights to keywords Search for matches in user’s networks Add extra semantic search capacity to existing resume databases 29
47. Semantic Search For Recruiters:User Interface Boolean search strings may look cryptic but they allow control over search A substitute UI needs to be friendly without affecting the quality of results Look for the right tool 30
50. Try it out for your purposes (industry, location, etc.) Extra points if it can “learn” or be tuned
51. See how it integrates with other tools you use
52. Check whether the UI is clear and friendlyYou may want to use several sourcing tools if they complement each other 31
53. Summary Use semantic search capacity of search engines and Social Networks Use general semantic search engines for research Review new semantic search tools for recruiters – start incorporating them into your recruiting strategy Expect increasing industry focus, adoption, and innovation in semantic recruiting in the months to come 32
