We extracted and processed abstract data from the Society for Neuroscience (SFN) annual meeting abstracts during the period 2001-2006 in order to gain an objective view of contemporary neuroscience. An important first step in the process was the application of data cleaning and disambiguation methods to construct a unified database, since the data were too noisy to be of full utility in the raw form initially available. Using natural language processing, text mining, and other data analysis techniques, we then examined the demographics and structure of the scientific collaboration network, the dynamics of the field over time, major research trends, and the structure of the sources of research funding. Some interesting findings include a high geographical concentration of neuroscience research in the north eastern United States, a surprisingly large transient population (66% of the authors appear in only one out of the six studied years), the central role played by the study of neurodegenerative disorders in the neuroscience community, and an apparent growth of behavioral/systems neuroscience with a corresponding shrinkage of cellular/molecular neuroscience over the six year period. The results from this work will prove useful for scientists, policy makers, and funding agencies seeking to gain a complete and unbiased picture of the community structure and body of knowledge encapsulated by a specific scientific domain.", "link"=>"http://www.mendeley.com/research/analysis-abstracts-presented-annual-meetings-society-neuroscience-2001-2006-12", "reader_count"=>35, "reader_count_by_academic_status"=>{"Professor > Associate Professor"=>7, "Librarian"=>3, "Researcher"=>10, "Student > Ph.

Here in terms of the data collection used it is not very clear whether by using only a single journal this can be guaranteed. It seems also likely that the authors provide a view of the research trends published in a given journal (journal publishing policy) rather than covering a whole domain. The structure of the abstract could also be improved. It is also not very clear what the actual use of the provided analysis would be in practice. Here a key issue is also whether the presented strategy be applied to other research domains. It is also not very clear whether this particular topic is suitable/of interest for the readership of PLOS One.\n\nIntroduction\nHere there authors do not mention several points, one is to provide a more in detail overview on previous work related to the presented research. The other is related to actually choosing the topic of neurosciences.\nIt is not clear why the authors used the abstracts only, and not the full text articles.\nThe authors mention the use of reputational indices but do not provide a corresponding reference. The authors should also mention previous work on co-author network extraction (there is at least one working online tool based on PubMed from the Gerstein lab) and also previous work related to citation network extracted from full text biomedical literature is missing. Regarding the monitoring of research trends, there are also several publications which could be mentioned here, e.g. related to research trends on genes and proteins (Hoffmann and Valencia). The importance of author ambiguity has also been addressed before by the WikiAuthors initiative.\n\nResults and Discussion\nGeographical Distribution\nHere are several aspects which are not very clear from the analysis carried out by the authors: how the authors group / define geographical regions and whether the location of the annual meetings has a significant effect on the number of publications from certain (geographically close to the meeting venue) regions. When the authors mention the top five countries, they should keep in mind that EU-15 doesn't correspond to a country. It is also not clear why they did not dissect Europe into the corresponding countries in this study.\n\nBasic statistics and demographics\nThis section lack a clear focus, many aspects are mentioned but it is not clear what the main idea the authors want to present in this section would be. The relevance of some of the mentions points is also not clear.\n\nAnalysis of the co-authorship graphs\nThe authors did a detailed study of the main characteristics of the resulting co-author network with interesting results. What is missing here is a clear motivation why this analysis is relevant , something which is missing in the current manuscript.\n\nTopic modelling\nAlthough the presented approach is interesting and LSI has been used successfully in terms of biomedical literature processing in the domain of microarray data analysis some aspects are not clear form the paper. It seems that the authors used stemmed words as basic input for their system. It seems that using only single words and not exploring additional aspects such as collocations, technical terms etc,.. can only show a partial picture of the relevant topics mentioned in the used abstract collection.\n\nTopic clusters\nThis is a specially interesting part of the presented work and would benefit from more details.", "isRemoved"=>false, "created"=>"2008-05-01T14:33:54Z", "lastModified"=>"2008-05-01T14:33:54Z", "creator"=>{"userId"=>"80539"}, "highlightedText"=>"", "competingInterestStatement"=>{"creatorWasPrompted"=>false, "hasCompetingInterests"=>false}, "parentArticle"=>{"doi"=>"info:doi/10.1371/journal.pone.0002052", "state"=>"published", "journals"=>{"PLoSONE"=>{"journalKey"=>"PLoSONE", "eIssn"=>"1932-6203", "title"=>"PLOS ONE"}}}, "replyTreeSize"=>0, "mostRecentActivity"=>"2008-05-01T14:33:54Z", "replies"=>[]}

These are the comments made by the referee when reviewing an earlier version of this paper. Prior to publication, the manuscript has been revised in light of these comments and to address other editorial requirements.\n**********\n\nLin et al present an analysis of trends in conference proceedings for the society of neuroscience (2001-6). Although some researchers don't like field trend analyses, I think they can be useful, especially at the policy-making level. The authors report some interesting trends and observations and, overall, I like this paper despite the fact that it is probably almost twice as long as it should be. However, I do have some concerns, both major and minor.\n\nMajor\np.3 The authors comment on the geographical concentration of authors on the east coast, southern cal, Tokyo, etc. Not too coincidentally, these are areas with extremely high population concentrations. I suspect that this trend is something that you will see at any international meeting. The authors sorely need to control for either population density in general (suboptimal solution, yet acceptable) or for the population of scientists in all fields from those cities (best solution, yet data hard to find). The most informative item to report here would be per-capita participation, which would reflect those areas that are *disproportionately* represented in neuroscience research.\n\np. 5: The authors engage in a lot of speculation as to what is causing the slowdown in the growth of meeting attendance. I think the most straightforward explanation is not even mentioned: Physical space limitations. Conference centers range in size, but quite often have an upper bound on auditorium capacity. The suggestion about hotel rooms I think may play a modest factor, but if the conferences are held in major cities, then I would think that unless it is during peak travel time (e.g. winter in Miami) then hotel capacity would not be a limiting factor because people can just stay at hotels further away from the conference center.\n\nFigure 2 I think would be more effective in conveying its point if it were plotted as lines on a graph that all added up to 100%, for the primary reason that from year to year it is not controlling for attendance in this graph. If the authors want to show how proximity and participation are correlated or changing, then they need to factor in # of people not just % change from the previous year.\n\nMinor\np. 1 \"Byzantine arrangement\"? I don't think it behooves the writers to speak in metaphors in official scientific publications.\n\np. 4: The authors mention that there are about 60% \"transients\", which is an interesting observation. What would also be interesting to know is if there are any correlations with geography, institution or even PI within this transient group. That is, is there a person or institution that tends to have a disproportionately high rate of people who enter and leave the field? They speculate, for example, that this is possibly because of blurred boundaries, but it seems like they have already compiled the trend analysis to answer this question, which leads me to wonder why they have not studied if the words in these 60% are on the \"fringe\" in terms of keywords or themes compared to all abstracts? The authors should flesh this out a little bit more.\n\nThe authors mention some of the more confounding facets of text-mining, the acronyms, the spelling variations, etc. They should comment on whether or not they think acronyms have confounded their analysis in any significant way. For example, if there are some acronyms that are particularly problematic in terms of the abstracts they have analyzed (e.g. NF stands for both neurofilament and neurofibromatosis, NA stands for nucleus ambiguous, nucleus accumbens and nucleus angularis, etc.).\n\nThe authors describe the 4 steps by which they resolve institutional affiliation. The obvious question, in my opinion, is why not just use ZIP code?\n\nIs Table 6 really necessary? *especially* since it's available online and can just be referenced?", "isRemoved"=>false, "created"=>"2008-05-01T14:35:13Z", "lastModified"=>"2008-05-01T14:35:13Z", "creator"=>{"userId"=>"80539"}, "highlightedText"=>"", "competingInterestStatement"=>{"creatorWasPrompted"=>false, "hasCompetingInterests"=>false}, "parentArticle"=>{"doi"=>"info:doi/10.1371/journal.pone.0002052", "state"=>"published", "journals"=>{"PLoSONE"=>{"journalKey"=>"PLoSONE", "eIssn"=>"1932-6203", "title"=>"PLOS ONE"}}}, "replyTreeSize"=>0, "mostRecentActivity"=>"2008-05-01T14:35:13Z", "replies"=>[]}

We extracted and processed abstract data from the Society for Neuroscience (SFN) annual meeting abstracts during the period 2001–2006 in order to gain an objective view of contemporary neuroscience. An important first step in the process was the application of data cleaning and disambiguation methods to construct a unified database, since the data were too noisy to be of full utility in the raw form initially available. Using natural language processing, text mining, and other data analysis techniques, we then examined the demographics and structure of the scientific collaboration network, the dynamics of the field over time, major research trends, and the structure of the sources of research funding. Some interesting findings include a high geographical concentration of neuroscience research in the north eastern United States, a surprisingly large transient population (66% of the authors appear in only one out of the six studied years), the central role played by the study of neurodegenerative disorders in the neuroscience community, and an apparent growth of behavioral/systems neuroscience with a corresponding shrinkage of cellular/molecular neuroscience over the six year period. The results from this work will prove useful for scientists, policy makers, and funding agencies seeking to gain a complete and unbiased picture of the community structure and body of knowledge encapsulated by a specific scientific domain.</p></div>", "links"=>[], "tags"=>["abstracts", "presented", "meetings", "neuroscience", "2001", "2006"], "article_id"=>150553, "categories"=>["Science Policy", "Information And Computing Sciences", "Mathematics", "Cancer", "Biological Sciences", "Neuroscience", "Medicine"], "users"=>["John M.
