Meandre 1.4.7 was released today, November 3, 2009. This is the last and most stable release in the 1.4 series before we move onto big changes for the 1.5 series. Version 1.4.7 has a few new features and numerous bug fixes and usability improvements.

As usual, the Download page now points to this stable release:

The raw artifacts are available at the SEASR repository:

Visible changes since 1.4.5 (Version 1.4.6 was an internal release):

* Meandre server can now load flows from the network and then be restarted and run offline.

* Improvements to the Meandre Administrative Interface for user accounts.

* Allow specification of the port when running a flow from the ZigZag console.

* Performance improvement on component installation by using MD5 checksums to check whether a particular resource already exist on the meandre server.

* When regenerating, downloading jar files is skipped if they already exist on the meandre server.

* Bug fixes.

Last night, I created a movie that walks through the process of installing the SEASR/Meandre tools and shows how to run the tools. You can check out the movie at If you listen closely you might even hear my puppy squeak a toy.

Loretta Auvil of the SEASR Team participated in a workshop at Colorado Learning and Teaching with Technology Conference (COLTT) at the University of Boulder on August 13, 2009. The workshop focused on the SEASR Analytics for Zotero, but also introduced the use of SEASR analytics for researchers data.

Loretta Auvil of the SEASR Team will be participating in a workshop at Colorado Learning and Teaching with Technology Conference (COLTT). The workshop takes place at the University of Boulder on August 13, 2009 from 1:30-3:45pm. The workshop will focus on SEASR Analytics for Zotero. You can register for the event at the COLTT website above.

This presentation will highlight the integration of two powerful tools–Zotero for data management and SEASR for analytics. Zotero was developed at the Center for History and New Media, George Mason University, and is a tool aimed at facilitating a user’s research process by providing mechanisms for collecting, managing, and citing Internet resources (websites, articles, books, etc.). Zotero functions as an extension of the popular open-source browser Firefox. One of the key features provided by Zotero is the ability to automatically extract metadata from online resources as part of the resource collection process and to store it conveniently. Zotero also provides advanced tagging and searching functionality, allowing the user to organize, find, and visualize the collected resources effortlessly.

SEASR provides a semantic-enabled web-driven dataflow-execution environment that allows others to create their own analytical components. The initial analytics are meant to be demonstrations to show capabilities such as tag cloud generation, sentence summarization, entity extraction, and citation network analysis of the selected data assets. Additional text analysis capabilities are forthcoming. SEASR provides analytics to enhance scholars’ use of digital materials by helping them uncover hidden information and connections, supporting the study of assets from small patterns drawn from a single text or chunk of text to broader entity categories and relations across a million words or a million books. These analytics are also provided as a Firefox extension. This application allows researchers to use the SEASR analytical tools with their Zotero assets in a straightforward way.

Bernie Ács of the SEASR Team made a remote presentation for the NINES/18th Connect Workshop held in Dublin on July 15, 2009. The presentation included an overview of the SEASR project. Also in remote attendance were Loretta Auvil and Xavier Llorà of the SEASR Team.

Loretta Auvil, Boris Capitanu, and Amit Kumar of the SEASR Team participate in THATCamp 2009 at George Mason University on June 27-29, 2009. We had the opportunity to have a session on SEASR Analytics. We also had the opportunity to discuss SEASR with many humanities researchers.


A new version (0.3.5) of the SEASR Analytics for Zotero Firefox plugin has been released. The new version adds support for Zotero 1.0.* – 2.0b5 and Firefox 2.0 – 3.5.*. A new set of flows (applications) are available, including: Flesch-Kincaid Readability Test, Tag Cloud Viewer, Date Entities to Simile Timeline, HITS Summarizer, and Author Centrality Analysis.

Our user community wanted a different naming strategy, so that one could tell what items were analyzed. If a single item is selected, then the results item maintains the same name as the item. If multiple items are selected, then the results item uses the collection name followed by the number of items selected. In both cases, the name of the service that is executed is provided in the “Creator” attribute. The selected items are also added to the “Related Items” section – a problem with populating these items was also fixed.

We made several changes to improve configuration file specification. One change includes the ability to specify a configuration file in XML format (json support still exists) with additional error messages to indicate problems with parsing your custom configuration file. This configuration file may exist on your local machine and you can use a file browser to find the local file.

Loretta Auvil and Bernie Ács of the SEASR Team participated in the Digital Humanities 2009 Conference at the University of Maryland on June 22-25, 2009. We had a poster called “SEASR Integrates with Zotero to Provide Analytical Environment for Mashing up Other Analytical Tools” by Boris Capitanu, Xavier Llorà, Loretta Auvil, Michael Welge, and Bernie Ács. We also had the opportunity to have discussions with many humanities researchers.

The SEASR Team held a Follow-up SEASR Workshop on the Monday, June 22, 2009 of Digital Humanities 2009 week. Loretta Auvil and Bernie Ács presented updates to the SEASR project. We had presentations from Andrew Ashton of Brown University, Clare Lewellyn and Michael Krot of JSTOR, Anoop Kumar of Tufts (VUE), and Susan Schreibman of Digital Humanities Observatory.

David Tcheng  and Amit Kumar represented SEASR project at the 19 June 2009 ACM/IEEE Joint Conference on Digital Libraries “Workshop On Integrating Digital Library Content with Computational Tools and Services” workshop. The two workshops presented were “SEASR & Meandre for Second Generation Digital Libraries”  and  “ NESTER – Web Based Waveform Analysis with Meandre”.

The presentation abstracts are available here and here.
