Apply for a Paid Internship at SciPlore – Summer 2014

In cooperation with the German Academic Exchange Service (DAAD), we are offering a paid internship for a computer science Bachelor student, who is passionate about prototype design and development. Prerequisite is that you are a student studying at a German university. More details on prerequisites here, download the project description as PDF.

At SciPlore you will be working with an international team of researchers, affiliated with the University of California Berkeley and the University of Magdeburg in Germany. As an intern, you will have the chance to spend 6-12 weeks abroad at a research institute collaborating with the SciPlore team.

The SciPlore team develops novel approaches in citation and semantic text analysis for quantifying similarities between scientific articles. Similarity assessments are crucial to many Information Retrieval (IR) tasks, such as clustering of documents, recommending academic literature, or automatically detecting academic plagiarism.

Below is a screenshot of CitePlag – the first prototype of a citation-based plagiarism detection system, which we developed. To see for yourself the document similarity visualization of CitePlag, use the system on a real plagiarism case that translated from Chinese, or on a plagiarized medical publication that was retracted with the help of CitePlag.

New release of SciPlore Mindmapping / Docear!

Version 1.0 is out now!

We’ve added several new features and made many improvements over the past few months.

See for yourself:

New user manual

To the download

For those of you still wondering…what is Docear?

Docear is a unique solution to literature management that seamlessly integrates mind map creation and a reference manager to easily organize the notes you made inside PDF documents and the annotations you made while reading. Docear’s approach helps you with all three steps of the reading – creative thinking – and writing process:

  • organizing your thoughts and annotations (mind map)
  • creating new documents (exporting outlines from mind map)
  • and discovering new academic literature (recommender system)

Docear does this in a single-section user-interface. This distinguishes the software from the interfaces of competitors, including Zotero, JabRef, Mendeley, Endnote, etc. in that it allows a more comprehensive organization of your e-literature (PDFs) and all the notes, highlights, comments, bookmarks, etc. you created while reading! Our goal is that you to never get lost or forget an idea again.

Docear’s ‘literature suite concept’ helps you draft and write academic articles, papers, publications, or books and theses by providing you with all the annotations you previously created right there at your finger tips! Docear works with standard PDF annotations, so you can use your favorite PDF viewer.

The literature suite concept also includes a recommender system that allows you to discover new academic literature. Docear is free and open source and offers many additional features, which you can check out here: http://www.docear.org/software/details/

CitePlag got a makeover

CitePlag is the first prototype of a citation-based Plagiarism Detection (CbPD) System.

The prototype was just recently demonstrated at this year’s SIGIR conference.

So what’s novel about CitePlag?

In contrast to existing text-based approaches to plagiarism detection, CitePlag does not analyze literal text matches alone to determine document suspiciousness – but rather, CitePlag makes use of the unique citation placement in the full-text of documents to determine similarity and detect potential plagiarism.

In examining citation placement, position, and order, CitePlag forms a text-independent / and even language-barrier transcending “fingerprint” of the semantic content of documents, which can then be used to detect potential unoriginality and plagiarism.

Chines_English_CitePlag

CitePlag has come a long way from it’s humble beginnings in 2010, when we first proposed a citation-based approach to detect semantic similarity between documents for use in plagiarism detection. A year later, we developed the algorithms, and today we have a working prototype available for public use!

CitePlag now received a new homepage featuring improved functionality.

You can:

  1. upload your own files  (PDF/ text documents)
  2. examine the most plagiarism findings and example of retracted plagiarism cases
  3. compare any two publications from the Open Access subset of the PubMed’s database  (200,000+ medical publications)

Test the CitePlag prototype for yourself at its new home on the web: http://citeplag.org/

If you’re curious about the project, see our related publications for more details on CbPD, or request a copy of the doctoral thesis of Bela Gipp, which narrows in on all aspects of Citation-based Plagiarism Detection.

First public version of Docear released (1.0 Beta 1)

Today, on February 15th, 2012 we released the first public version of Docear. It’s a Beta version and still has some bugs and missing features but overall it will give you a thorough impression of what we consider an academic literature suite should be.

The main idea behind Docear is that you annotate everything you consider important in a PDF. That means, you highlight text, write comments, or create bookmarks in the PDF. To create bookmarks and comments, you can use almost any PDF reader (highlighting text is a bit more complicated). These PDF annotations are then imported by Docear to a mind map. In this mind map you can organize all your annotations into categories, create further nodes and add more text. With the integrated reference manager, bibliographic data can be added to each of the PDF annotations (and all other nodes in the mind map). Subsequently, you can create a new mind map, drag e.g. a research paper, copy your annotations to the draft and if you need more information you just click on the PDF annotation and the PDF will open on the page the annotation was made. Watch this video to get a better idea of what Docear can do (watch it in full-screen mode).

Here is again an overview of the major changes between Docear and its predecessor SciPlore MindMapping.

Freeplane instead of FreeMind

The old SciPlore MindMapping was based on FreeMind, a good and popular but not very well maintained mind mapping software. The new Docear is based on Freeplane, a really exceptional piece of software. Freeplane has many more features compared to FreeMind (e.g. Free floating nodes, displaying images), is faster, more stable and above all: Freeplane has a great plugin system that allows us offering Docear as a plugin for Freeplane. That means, if a new version of Freeplane is released you can just install it and Docear will work with the new version. You do not need to wait until we have adjusted Docear to the new Freeplane version. Also, the Freeplane development team is highly responsive to user feedback. If you have ideas for new features regarding the mind mapping functionality, the Freeplane team will be happy to hear them.

Integrated Reference Manager

Docear has it’s own BibTeX compatible reference manager. Or better said: we fully integrated one of the best available reference managers, namely JabRef. That means you can directly create references in Docear, add them to nodes (even if they don’t have a link to a PDF), edit references in the mind map and they will automatically be changed in the BibTeX file, and you have all the wonderful standard features that JabRef offers. Of course, you can still install JabRef in parallel and work as you are used with SciPlore MindMapping.

Compatibility with other reference Managers

You don’t have to use our integrated reference manager. You can still use any other BibTeX compatible reference manager as well and also our support for Mendeley now is improved. It is no problem to use Mendeley for managing your PDFs (and extract metadata) and use Mendeley’s BibTeX file in Docear.

Workspace

Docear has a “workspace”. We believe this workspace makes Docear much easier to understand for new users. In the workspace you have several mind maps. For instance, one that lists only your new PDF files. Another one is for managing all your annotations, another one for your own publications. Of course you can still create new mind maps for each of your assignments, papers or books you are currently writing. There is also another advantage of having a workspace. All links in mind maps are set relative to the workspace. That means you can move your mind maps within the workspace and all links to PDF files will still work. It also allows you to use your data on several computers with different operating systems.

MS Word plugin

The probably biggest advantage other reference managers such as Zotero and Mendeley have over Docear is their good integration with Microsoft Word and OpenOffice. For SciPlore MindMapping we recommended using BibTeX4Word but BibTeX4Word is not very user friendly (neither the installation, nor the use in MS Word, nor installing new citation styles). We are working on a Docear4Word Add-On and hope to have it ready in a few weeks.
