Optimal matching (OM) is a method for measuring the similarity between pairs of sequences (e.g., work histories). This article discusses two problems with optimal matching. First, the author identifies a flaw in OM ‘‘indel costs’’ and proposes a solution to this flaw. Second, the author discusses the need for benchmarks to measure the added value of OM and to test competing versions. To that end, the author conducts an empirical test of traditional OM, the alternative localized OM, and sequence… Expand

A Transition-Oriented Approach to Optimal Matching
TLDR
This paper introduces a distinction between two sequence types—namely, common ancestors and unfolding processes and presents a new way of coding sequences as an extension to conventional OM analyses and demonstrates its usefulness in simulated and empirical examples. Expand
Analyzing Sequence Data
TLDR
Optimal matching (OM), an invaluable yet underutilized tool in the analysis of sequence data, is discussed and an illustration of its use in the examination of careers of deans at U.S. business schools is provided. Expand
Optimal Matching Analysis in Career Research: A Review and Some Best-practice Recommendations
Optimal matching is a method for the analysis of sequential data. It allows researchers to detect patterns in career sequences or occupational trajectories. We first give a brief introduction to theExpand
What matters in differences between life trajectories: a comparative review of sequence dissimilarity measures
TLDR
The study shows that there is no universally optimal distance index, and that the choice of a measure depends on which aspect the authors want to focus on, and introduces novel ways of measuring dissimilarities that overcome some flaws in existing measures. Expand
Three Narratives of Sequence Analysis
How do we relate the distance between two sequences, as given by an algorithm such as optimal matching, to sociologically meaningful notions of similarity and dissimilarity? This has beenExpand
A comparative review of sequence dissimilarity measures
This is a comparative study of the multiple ways of measuring dissimilarities between state sequences. For sequences describing life courses, such as family life trajectories or professional careers,Expand
Optimal Matching Scores for Sequence Alignment in Community Detection
Building a similarity network to relate consumers using sequence alignment algorithm requires setting the indel scores, representing gap insertion or deletion of portions of the sequence, as theseExpand
An apple doesn't fall far from the tree—Or does it? Occupational inheritance and teachers' career patterns
Based on 15 years of employment and job mobility data from a sample of Swiss primary school teachers (N = 999 in three cohorts), we use optimal matching analysis (OMA) to identify six career patternsExpand
TITLE WeightedCluster Library Manual : A practical guide to creating typologies of trajectories in the social sciences with R Technical report
This manual has a twofold aim: to present the WeightedCluster library and offer a step-by-step guide to creating typologies of sequences for the social sciences. In particular, this library makes itExpand
WeightedCluster Library Manual A practical guide to creating typologies of trajectories in the social sciences with R
TLDR
This manual presents the WeightedCluster library and offers a step-by-step guide to creating typologies of sequences for the social sciences, and shows that these methods offer an important descriptive point of view on sequences by bringing to light recurrent patterns. Expand
