focusing on the individual: find, build, suggest
DESCRIPTION
Grande parte da comunicação científica é centrada no indivíduo. Como pesquisadores, exploramos outros trabalhos de autores de artigos interessantes; como editores, selecionamos revisores especialistas em áreas particulares; como financiadores, buscamos pesquisadores com currículo comprovado. Apresentarei aspectos do Google Acadêmico com foco no pesquisador individual. Descreverei nossa abordagem para a desambiguação de autores, permitindo mesmo a autores prolíficos criar rapidamente um perfil com todos os seus artigos. Apresentarei a integração dos perfis de autores individuais nos resultados de busca do Google Acadêmico, que facilita a exploração de outros trabalhos de autores-chave pelos usuários. Por fim, descreverei nossas recomendações personalizadas, que analisam publicações de um autor para identificar automaticamente artigos recentemente publicados, que possam ser de seu interesse. Much of scholarly communication is centered around individuals. As researchers, we explore other work by authors of interesting articles, as editors, we seek out reviewers knowledgeable in particular areas, as funders, we look for researchers with a proven track record. I will present features in Google Scholar that focus on the individual researcher. I will describe our approach to author disambiguation which allows even prolific authors to quickly set up a profile with all their articles. I will present integration of individual author profiles into Scholar search results which make it easy for users to explore other work by key authors. Finally, I will describe our personalized recommendations which analyze an author’s publications to automatically identify recently published articles that are likely to be of her interest.

Science is anchored by scientists
Keeping up with significant advances
– We look for recent work by key authors
Evaluating quality of new research
– We identify & invite experts to review
Funding impactful research
– We look for investigators with a proven record
Scholars on Google Scholar
Challenges
– Identify publications by an author
– Keep them up-to-date
– Pivot from articles to authors and back
Opportunities
– Find me what I need to read
– Identify key researchers in areas
Overview
Author disambiguation
– Quickly setup author profile, auto-maintain
Integration with Scholar search
– Work by key authors
– Find experts in an area
Personalized recommendations
– Find me what I need to read
Author disambiguation approach
Build a statistical model grouping articles by an author with the same name
– Author lists, journals, co-authors, research area, affiliations, text of articles
– Multi-dimensional model
– Shoot for high precision, very good recall
Disambiguation approach – II
Many authors work in multiple areas
– With multiple co-authors, multiple communities
– Trying to group these results will break others
Allow such groups to remain separate
– Make it trivially easy for authors to merge
Final disambiguation step is human
– Key is to make the human step very simple
How does it work? Present groups of articles matching name
– Author selects groups written by her
After setup, updates are automated
Author can merge/add/remove
Changes fed back into the statistical model
– Improves update precision & recall
– Automated => must be hi-precision/hi-recall
What do you get?
List of all your publications
Citation metrics – overall and per article
Links to co-authors
Follow all your citations
Colleagues can follow your work
Personalized recommendations
How well does it work?
Worldwide adoption
– Widely published and cited authors
– Most authors take a few minutes
– Most authors opt for automated updates
– All countries, all areas
Why does it work? Statistical model is quite effective
– Able to achieve high precision
– Recall tradeoff is small
– Flexibility to split groups key, but not frequent
For most authors takes 5-10 minutes
– Effort is one-time, updates are automated
Enables many useful services – well worth the few minutes!
Finding Scholars
Queries including name
– Add matching author profiles as results
Keyword queries
– Link author names to author profiles
Browse researchers in an area
– Link author interests to search over profiles
Personalized recommendations
Challenge: keep up with rapid growth in articles
Approach:
– Centered around author profiles
– Analyze research interests & evolution
– Factor in co-authors & their evolution
– Leverage citation graph
– Scan all newly seen articles
Finally… Individuals key for recovering structure
– Allow efficient, cascade-able disambiguation
– Depts, institutions, funding agencies
– Most other analyses can be layered on top
Find what I need to read – classic hard problem
– Much progress, much much more to do
