Web API

• API (Application Programming Interfaces)• Allows different components of software to

interact and exchange data.• Basically, a platform that facilitates mashups.– Mashups are services that combine 2 or more

other web services into one.• Eg: Foursquare, which allows you to “map” and “share

on other social media” your location.


Collective Intelligence

• CI is when people from around the world collectively contribute their expertise/intelligence to a topic.

• Formal definition:– The notion that distributed groups of people with

a divergent range of information and expertise will be able to outperform the capabilities of individual experts.• Eg: Wikipedia


Semantic Web

• The Semantic Web is a set of design principles that will allow computers to be able to better index Web sites, topics and subjects.

• Semantic is the study of meanings.• Simply, semantic web, is the indexing or

grouping of similar pages by topic.– Google Search is the best example of semantic

web in action. The retrieval of pages that relate to the “searched” topic.


Groupware

• A class of software that enables people to work together more effectively is called groupware.

• These tools are becoming more common in organizations and include email, work flow automation systems, group calendars etc.


EMS: Electronic Meeting System

• An EMS is a collection of computers networked together with sophisticated software tools to help group members solve problems and make decisions.– Eg: Videoconferencing (Cisco)


Metadata

• Metadata is data about data.• It describes data in terms of who, where,

when, why etc.– Eg: Word Documents contains metadata about

the Author, size and time the doc was created and last modified.

– In photos, it would include the size, date and time, camera type, etc.


Geotagging

• Geotagging is the geospacial metadata (latitude, longitude and in some cases altitude) that is added to data such as photos.

• The most common geotags are included on photos and videos that are posted on Social Media sites such as Facebook and Twitter.

• Geotags are fundamental to the Foursquare site.


Cloud-based Collaboration Tools

• These tools facilitated collaboration and allow for easy access and easy transfer of documents or other files from one person to another.– For example: Dropbox, Google Drive, Microsoft

Skydrive• Documents are not only stored online but can

be downloaded, modified and uploaded to the ‘cloud’.


Crowd Sourcing

• The practice of obtaining services or content by ‘outsourcing’ work to a ‘crowd’ of people.– Eg: Wikipedia utilizes crowd sourcing to maintain

a easy access encyclopedia.• Quality of work is higher in crowdsourced

information as more heads are better than one. “By canvassing a large crowd of people for ideas and skills…the quality of content…will be superior.”

Viral Marketing

• The promotion of websites, products or services through the use of the ‘network effect’ to increase reach.

• Over time, viral marketing has shifted from banner ads and spam to other forms of advertising that entice viewers to share / spread the word via email or social networks to their ‘network’


Pitfalls of Web 2.0 Marketing

• Online Product Reviews– Negative reviews from competitors– Companies paying for positive reviews

• Microblogging– Easy to “cross a line” and offend– Negative publicity can come quickly

• Social Networks– Fine line between maintaining control and offending

customers– Individuals sharing too much personal information


More Pitfalls of Web 2.0 Marketing

• Bad Vibes going Viral– Negative publicity can spread like wildfire– Videos can easily go viral

• Lessons Learned– News travels fast– Have a crisis team and a plan– Prepare for your worst social media nightmare– Monitor the environment– Respond within 24 hours
