The technologies that we are developing relevant to matching candidates to jobs can be split in four key areas
1 Pre processing unstructured text leading to structured information
2 Using metadata to aid matching
3 Vectorial Semantic Analysis
4 Vectorial Semantics on Structured Data
Today lets look at number 1.
By using semantically enabled systems, we are able to take unstructured text (such as a Job Ad or CV) and extract valuable information. This is often called metadata. Semantics, along with other core Artificial Intelligence technologies, allows us to do this by enhancing the systems ability to understand the text. The technique effectively creates structured and enhanced information in a common form that can be used to significantly enhance a systems abilities to match Jobs to candidates.
We are using semantically enabled parsers in four areas to allow us match jobs to candidates and plot them all on a map.
• finding a company website and location details so that we identify job vacancies with a company and location
• Intelligently browsing a website to locate job pages by identify the routes to possible job pages semantically
• Parsing possible job pages, deciding whether the page is a job or not, finding the location, extracting all the relevant information about the job (skills required (soft and hard), Job title, Job Sector (engineering medical etc) , storing all this relevant information and then plotting the job on a map
These first three uses together we have called Semantically Enabled Intelligent Job Mining and effectively constitutes our search engine for jobs
The fourth process is a CV parser. After extracting the details of the candidate, deconstruct the CV into its constituent parts (e.g. Employment Records, Education , Skills, References etc) and building up a profile of the candidate. Using our advanced technologies we can extract much detail. Take the employment record below, for instance:
Project Manager (Aug 2006–Jun 2008)
My First Company Ltd London, UK
Was the project manager, for the charity’s Drugs Awareness project, the project’s aim was to educate the local community on the effects and wide reaching effects of Drug Abuse/misuse.
Recruited a motivated, dedicated project team.
Prepared the Project Soft-Launch and developed the project to fruition.
Our system conveniently stores the facts that our candidate was a project manager for nearly 2 years. The candidate worked in the medical sector and has specialism’s in Drugs Awareness and Abuse. Finally identifying that during this 2 year period, our candidate was also involved in recruitment and project development.
Stay tuned for numbers 2, 3 and 4.

Geographic mapping is unique in its intuitive ability to communicate patterns in information. This was once the sole preserve of the specialist geospatial analyst. Today, with the introduction of online mapping, such as that from Google and Microsoft, web designers all over the World are now putting markers onto maps showing their office locations. Consider replacing this small table of data behind the online map with a massive database of information and business intelligence, and coupling this with search, visualisation, communications and computation logic.
In this document, we present a profile of this market and the new opportunities that true web-GIS brings, delivering high functionality, cost-effective, interactive online mapping applications for private or public consumption. Web-GIS can take the ability to analyse and extract information from your data to the very point-of-need. At the same time, online mapping can be used to share appropriate sections of this information with the public and provide a platform for the public to communicate back issues of importance.
Essentially, a Geographic Information System (GIS) comprises a store of base maps, a map server capable of accurately displaying the appropriate part of these maps together with overlays of data, and the computational functionality to process the data for these overlays from your raw data. These base maps will typically cost many thousands, if not hundreds of thousands, of pounds, per year in license fees.
Traditional GIS systems have been around for over 20 years and are typically expensive, high-end functionality, systems requiring massive processing capability and highly skilled staff to program and operate them. They allow for any degree of geographical analysis to be applied to huge datasets, with millimetre accuracy. Because of this they are commonly used by a small number of specialist staff to deliver on requests from other departments. Typical applications include oil exploration, flood modelling and the mapping of utility pipes and cables.
Increasingly, GIS is being applied to far simpler datasets, employing less then 10% of the capability of the system. There is also a desire to put the power of analysis into the hands of the people that require the results, or to publish results for the public. This becomes prohibitively expensive in terms of the licenses for GIS software, the detailed base mapping and the skilled staff to develop and manage the system.
Online map servers
Google introduced their online map service in 2005 and it has since been joined by Microsoft’s own service. These online map servers deliver the GIS function of displaying an appropriate part of a base street map, terrain map, satellite or aerial imagery to a website at a vastly reduced cost, if not free.
These do not have the resolution accuracy of traditional GIS and don’t display the detail available on such as Ordnance Survey’s Master Map layers, but for the majority of applications this isn’t required. Online map servers deliver web-optimised performance for thousands of simultaneous users, with adequate accuracy, and global mapping. Additionally, they are already familiar to most users and very simple to use.
Increasingly, there is recognition that online mapping is being used for business critical applications. Google, for example, have two levels of license, one allowing for free access for public service applications, and a ‘Premier’ license that comes with a service level agreement and business friendly terms and conditions, supports high traffic levels, additional security options and has no advertising.
Online mapping – web design
Application Programming Interfaces (APIs) are well documented and freely available for these online map sources, making it very simple for a web designer to integrate a map into their website and to overlay basic information, such as putting markers onto the map to show where stores are located. These implementations can be made very easy to use and work well for large volumes of users.
Another option available to the web designer is to by-pass the use of an online map server and to create images of country and regional outlines using Flash, using this as a navigator for other data on their site.
Whilst bringing the power of maps to the communication and navigation of information, these applications are inherently limited to relatively simple, inflexible data structures. They are good for illustration but not for analysing or interacting with the data itself.
There are many mapping applications that have not previously been realisable, either because they require a level of functionality not available for large user-base applications, or because they are too expensive to develop using traditional GIS processes and systems. True Web-GIS opens up new opportunities to realise these projects both for public access over the internet or private access over a local network.
Zubed’s true web-GIS systems bring traditional GIS functionality to online applications and can be quickly and economically developed, using online map servers. These systems put a database behind the base mapping and apply proprietary technology to manage massive data volumes. A modular, customisable, capability allows the user to search / filter the data to be displayed, select from different display types, and apply communications and computational logic. Data can be updated at any time using a simple upload function or connected to a customer’s live systems via web services or other API processes.
As well as being able to display specifically the data of interest, in the most accessible way, these systems allow users to extract the sub-set of information that they are most interested in, directly from the map, for use in any other analysis or publication application. By this means, analysis is being taken to the point-of-need, removing the need to request results days ahead of when it’s needed, and to even perform ad-hoc analysis of up-to-the-minute information whenever questions arise.
Comparision of GIS systems
New opportunities provided by true web-GIS, such as Zubed’s systems, enable the cost-effective production of highly accessible online GIS applications.
Bringing GIS to the web allows for a highly interactive experience. Users can communicate with the information behind the system, posting new data, drawing active geographic regions and extracting selected data for further analysis or application elsewhere.
With rapid outsourced development of a customised solution, based upon pre-tested functional modules, and the use of economic, globally consistent, online mapping, there is no need to recruit specialist contract or permanent staff, either to develop or administrate the solution.
Using online mapping, such as that from Google and Microsoft, which is familiar to most users and optimised for the delivery of web-based solutions, web-GIS brings analytical functionality to the point-of-need and out of the specialist geospatial division.
